The SU-9915 is a direct replacement for the stock GSXS air filter

If you ride one of the three versions of Suzuki’s GSXS 1000, you know all about “smart money.” The GSXS packs a lot of performance and ergonomic sensibility into a package that is reasonably priced for a lighter sport bike. It’s only logical that the smart money attitude of GSXS owners would continue with the maintenance and performance enhancements to the bike. A K&N replacement air filter sits at the top of the list of performance upgrades to Suzuki’s fine mount.

The air filter SU-9915 will help the GSXS breathe freely and efficiently through Suzuki’s Dual Throttle Valve 44mm throttle bodies. Like every K&N performance air filter, the SU-9915 is designed to increase horsepower and torque. This affordable upgrade comes in a form that is a direct replacement for the restrictive stock filter and it requires no further modification. It drops directly into the factory air box. It must be emphasized that installing a K&N filter will, in no way, affect your Suzuki’s warranty.

A look at the legendary K&N filtration media

The “smart money” theme is continued with the washable and reusable nature of the filter. Over the life of the GSXS, the SU-9915 will be the last air filter you’ll ever need. On a bike like the Suzuki that makes performance riding comfortable, it’s easy to rack up the miles. K&N’s Million Mile Limited Warranty will be in your air box for all of those miles! The reusable design of the K&N filter is not only good for your pocketbook; it’s great for the environment.

The SU-9915 comes pre-oiled and ready to install

Attention to detail is the earmark of K&N’s engineering prowess, and the SU-9915 is no exception. The multiple layers of pleated, woven cotton gauze media not only provide increased airflow, but also highly effective filtration. The filter is designed with a base seal and sealing bead that is specific to the GSXS to help eliminate the chance for unfiltered air infiltration. The SU-9915 comes pre-oiled and ready to install. When it comes time to clean the filter, which you can do once a year or more often if you’d like, K&N offers the 99-5000 air filter cleaning kit. Using the included cleaner and oil, cleaning and re-oiling the filter will be one of the simplest forms of maintenance you can do.

Sport motorcyclists are always looking for smart, effective, and reliable upgrades. The logical starting point for performance enhancement is on the intake side of the equation. Whether you ride the standard, the ABS, or the fully-faired incarnation of the GSXS 1000, the SU-9915 is the smart choice for your air filtration needs.

The SU-9915 fits these Suzuki models:
2016 SUZUKI GSXS1000F ABS 999
2016 SUZUKI GSXS1000 ABS 999
2016 SUZUKI GSXS1000 999

The K&N 33-2029 engine air filter will replace the stock air filter and is constructed of a special cotton gauze that presents a greater surface area to trap more dirt and other particles.

Audi owners are part of a storied automotive design and engineering fraternity, and if you own a 20th century example built between 1987 and 2000, you appreciate it as a legacy car, a vehicle at the top of the sporty, sophisticated driving scene of its time. A number of models from that 13-year period have been voted "best of all time" by web entities such as Ranker and Complex.com, which use input from fans and experts, requiring voters to have the car's practicality, reliability, and performance in mind, and their community-based survey results seem quite relatable. Especially appreciated are the A6, the 1989, 1990 and 1991 Audi 80s, the 1986, 1989 and 1990 Audi 100 Sedans, the 1991 Audi 90, and 1996-98 Cabriolets.

Of note are Audi's innovations from that time, such as aerodynamic flush windows in the C3 100 of 1991, and a fully zinc-dipped, galvanized body for the new type 89 in 1987 (also called the 80 and 90, in North America), which are design and manufacturing practices still in use today.

Development of both lightweight, high-performance diesel- and gasoline-powered engines at this time revolved around Audi's in-line four- and five-cylinder motors from 1.9 to 2.3 liters in size, plus new 2.6- and 2.8-liter V6s and a new 1.9-liter TDI (turbocharged direct injection) diesel. It was quite a range that was mostly available only in Europe, but North America did get the V6 and TDI.

The Coupe and Cabriolet came along in 1988, based on the Audi 80 platform, and the 1990 Coupe made it to North America as a Quattro GT car with the 20-valve, 1.3-liter 5-cylinder engine. The Cabriolet, based on the Coupe, and Audi's first convertible since 1959, was powered by the 2.8- and 2.6-liter V6s.

Although emissions and old-car regulations keep many vehicles over a certain age off the roads in Europe and the UK, yours is a survivor, and that is because you've maintained it well and driven it carefully. Among those maintenance details is the engine air filter service which has been made simpler and easier for some time by utilizing the K&N 33-2029 washable, reusable engine air filter.

An engine air filter service is something you can easily do yourself, or you can order up the K&N 33-2029 filter and 99-5000 cleaning kit for your mechanic, and be assured you are giving your early-generation car the best protection on the planet.

The range of engines for the specific 1987-2000 Audis listed below is varied, but those included all share the same basic air box shape and dimensions that can hold the same open-top, rectangular air filter that can be replaced by the K&N 33-2029. Why keep buying disposable air filters when you're in preservation mode with your elder Audi?

K&N engine air filters are designed and engineered to replace the stock air filter and are constructed of an oiled, cotton gauze filter medium that presents a greater filter surface area to trap particles and bring more air to the engine. The filters are designed to provide more horsepower and torque for crisper throttle response, a plus for any iteration of your favorite marque.

The 33-2029 is recommended to be cleaned at 50,000 mile intervals, depending on driving conditions. It also can be cleaned more often if you wish. The process is very easy and requires only simple hand tools. A set of printed instructions accompany each K&N filter, and depending on your model, there are also videos available online to walk you through the procedure.

The best way to clean this filter is with the K&N 99-5000 filter care service kit. Spray the filter with Power Kleen spray, rinse in clear running water, let it thoroughly air dry, then re-oil it with a few sprays of the air cleaner oil before refitting. Or you can simply specify the K&N 33-2029 filter and 99-5000 cleaning kit to your mechanic for the next scheduled service.

You appreciate what your vintage Audi can do for you daily and what it has done throughout the decades on road and track. The engineering successes and innovations built into your passenger car makes it a superior road-going vehicle that you can love forever. To ensure that your Audi stays reliable, invest in the K&N 33-2029 engine air filter, which is backed by K&N's 10-year, Million Mile warranty.

When you're ready to buy a K&N replacement air filter, first use K&N's online search by vehicle tool, then visit an authorized K&N dealer, who can be found worldwide using the K&N dealer search.

The RK-3932XB intake on a Harley-Davidson

Harley-Davidson motorcycles often respond more profoundly to simple performance modifications than motorcycles with other engine configurations. In stock form, Harley-Davidson engines are “under stressed.” What that means is that the engines are designed for a rather conservative balance between reliability and pure performance.

That’s where K&N’s RK-3932XB comes in. The product is one of K&N’s Street Metal series high-flow air intake systems. In short, the system helps your Harley® breathe freely resulting in a potentially substantial power advantage. The RK-3932XB is a complete intake system that replaces the restrictive stock unit. The air filter in the system is extra tall, which markedly increases airflow. The oiled cotton gauze filter media not only increases flow, but it also extends service intervals. You know you’d rather be riding your Harley than servicing it.

Installation of the RK-3932XB could not be more straightforward. The custom aluminum backing plate and vibration absorbing gasket fit securely to the throttle body and feature an internal-run breather system. Once installed, you can realize an estimated 7 horsepower gain at 4662 RPM (as dyno tested on a stock 2016 Harley-Davidson Dyna Switchback 103 ci). That performance boost is the kind you’ll feel instantly. Interestingly, that horsepower gain is more than the first Harley-Davidsons produced in total! The intake unit is especially well suited for custom or large engine builds that truly need that extra airflow.

The clean lines of the RK-3932XB intake system

The air filter unit on a Harley is a centerpiece of the engine design so it has to be good looking. The RK-3932XB has a subtle, clean appearance. The iconic K&N red-oiled filter media is visible behind the understated black intake cover. The overall aesthetics of the intake speak to its “all business” design and performance.

It should be noted that over the life of the motorcycle, a K&N washable filter is a cost effective alternative to restrictive, disposable filters. Moreover, in a time when our landfills are being loaded with throw-away maintenance items, a reusable K&N filter such as the E-3986, which is the part number for the filter, is an environmentally responsible choice.

The RK-3932XB is made in the USA and is covered by K&N’s exclusive Million Mile Limited Warranty. With easy installation, proven power gains, extended service intervals, good looks, and legendary K&N quality, the RK-3932XB is a great option for Harley-Davidson owners who want more out of their V-twin.

The RK-3932XB is simple, bolt-on performance for your Harley

The RK-3932XB fits these Harley-Davidson models:

Milton Peters’ stunning Green Monster is protected by legendary K&N filtration

Milton Peters’ stunning chopper is named after the iconic left field wall in Fenway Park. The bike’s designer and builder says he has always been a “huge Boston Red Sox fan.” In reality, Peters’ “Green Monster” shares very little in common with its namesake other than color. Fenway’s version is tall, stationary, and silent. Peters’ version is low, fast, and anything but quiet.

Leaving well enough alone is not in Peters’ DNA. “I started building, modifying and ‘chopping’ anything with wheels as a kid and then into my teenage years,” he reflects. Even with the success of his Green Monster, Peters is quick to deflect the label bike builder. “I was never a bike ‘builder’ until this project. There are plenty of custom parts on the bike, but I am still more of a novice assembler and far from the talents of many amazing builders. The amount of respect I have for any builder / assembler or even the everyday repair gurus is very high.” While Peters’ humility is refreshing, the quality of the build and the incredible visual unity of the chopper speak to a deep-rooted talent.

Serious work went into these exhaust bends, and it was worth it

In reality, the lion’s share of Peters’ customization experience has come on four-wheeled vehicles. “I have built and customized import cars that were featured in international magazines and even built an Isuzu Pup mini truck and fabricated my own body drop and installed my own hydraulics despite never have used a torch or welder before, and created a full custom stereo. I have been more heavily involved in the aftermarket automotive, recreational vehicle, and electronics scene for about 20 years now.”

According to Peters, the Green Monster is a product of about 15 years of thought, planning, and mental incubation. All of that rumination is evident in the overall aesthetic unity of the creation. Let’s start with the paint. As for all those green bits on the chopper, Peters says, “I wanted the paint to be candy for sure. I wanted the paint to scream ‘extreme’ yet not be too busy.” The color is not the end of the visual feast as Peters thinks his paint details make the difference. “I feel that this custom candy green paint, the skull on the tank, the flames and then all of the small elements that match throughout the entire bike, are what makes this bike different.”

The K&N filter inside that intake helps those big jugs pump out serious horsepower

Peters knows that a great chopper is not just about paint, despite the societal influence of what he calls “the commercialized chopper scene.” While that fad has faded, Peters is quick to point out that chopper building is alive and well. He says, “There are still plenty of shops, plenty of garage projects, or even people like myself who just finally said, ‘I am going to do this and I am doing it because I want to.’” The details of the Green Monster go much deeper than that paint.

The bike’s exhaust is a primary styling, performance, and auditory element. Getting the pipes just as Peters wanted them took some work. “I wanted the old school, heat wrapped look while having a slight ‘up sweep’ to it and of course an aggressive idle and rumble. I took a new exhaust and heated the bends. First, I had to get the exhaust past the housing, and I also wanted to sweep it up and out more. Next, I heated both pipe ends and brought them together slowly. I made a new bracket to mount them together and it works out visually and sounds exactly how I want it to.”

Attention to detail is everywhere on the Green Monster

Peters wanted other design details to “match and be stand out items, but be subtle.” Many of those details are machined to match the chopper’s distinctive rims. The brake rotors and drive pulley are cut to match the wheels. Proving no detail is too small, even the valve stems are machined to match. “The bike features a black frame with a good combination of chrome, black and aluminum throughout.” Peters continues, “The S&S intake with the K&N filter even has a chrome housing and I added in the black accent cover to the face of that. It is pretty clear that I wanted the bike to flow nicely. I feel the bike has a great balance of the three metals - chrome, black, and aluminum.”

So what about the engine in the beast? Well it’s impressive. The big twin pushes a displacement of 127 cubic inches. It has forged pistons and roller rockers. The power-plant produces approximately 160 horsepower and more than 150 foot-pounds of torque. It delivers that power to the road through a 6-speed, right-side drive and an open primary with a 3.5 inch belt drive.

The sexy lines of Milton Peters’ creation are the result of years of visualization

Peters trusts K&N to protect his fire-breathing labor of love. “I truly have used K&N for many years. My first oil filter and air intake were K&N back in 1997. I have trusted them ever since. The washable and re-usable part is nice but to me the performance and instant throttle response I feel from the K&N air filters and intake systems is worth it all. In my daily drivers and in my motorcycle, I know I can trust the all of the K&N filters to perform.” Of course, K&N has a full range of filters and intakes for your particular project. Use the online application tool to get what you need.

With the Green Monster complete, what’s next for Peters? “I have contemplated selling this chopper and building another; maybe a bagger. But then literally every time I look in my garage I smile. So I am often torn. That being said, I also think I may build something again with 4 wheels, maybe a hot rod, muscle car, or extreme 4X4. The jury is still out.” Whatever Peters decides to tackle next, rest assured that it will be unique, it will be fast, and it will be fitted with K&N products.

Noah Gragson in the No. 7 car leads the field in the NASCAR K&N Pro Series West race at the Utah Motorsports Campus

Noah Gragson swept the K&N Pro Series West doubleheader at the Utah Motorsports Campus and returned to victory circle for the first time since June.

“It feels good to sweep the weekend,” Gragson said. “This is what we needed. Heading off to the next race, we got a road course in the East Series. I’m just really pumped up right now.”

Gragson, one of the NASCAR Next drivers, won the first race after leading the last 10 laps of the Utah 110 presented by Ken Garff Volvo. He won the second race taking the lead on the last lap of the race.

“This is pure, never give up attitude,” Gragson said. “We really need this as a team. I am just so pumped up for all my guys, they worked real hard for this.”

Noah Gragson, center, won the second of two NASCAR K&N Pro Series West races at the Utah Motorsports Campus. Todd Gilliland, left, was second, and Ryan Partridge was third

In the first race, Ryan Partridge won the pole and led the first 22 laps of the K&N Pro Series West race. Rookie Todd Gilliland, the leader in the K&N Pro Series West standings, passed Partridge on lap 23 and was out front for three laps.

Gracin Raz was third, followed by Julia Landauer in fourth and Riley Herbst in fifth.

Gragson took the lead from Gilliland on lap 27 and won the race by 1.086 seconds. It was Gragson’s fourth win of his K&N Pro Series career. He won the K&N Pro Series East race at Stafford Motor Speedway in Connecticut in June.

“Made my way into second chasing the 16 car (Gilliland),” Gragson said. “He made a mistake down in turn 1 with probably 11 or 10 to go. I took away the lead and I think that was the game-changer in the race. That’s what changed everything. Got some momentum on our side just being the leader. He really burned his stuff up there trying to run me down. He’d get close and then blow the corner, get close again and blow the corner.”

Gilliland said his inexperience on road courses mixed with his aggressive strategy to catch Gragson cost him in the race.

“It’s my first road course. It’s no excuse,” Gilliland said. “I kind of overdrove it, kind of got off track. I let the 7 (Gragson) pass me. I got back to him and I overdrove it again and let him get away.”

Noah Gragson won the NASCAR K&N Pro Series West at the Utah Motorsports Campus. It was the fifth K&N Pro Series win of his career. He won the K&N Pro Series East race at Stafford Motor Speedway in Connecticut in June

In the second race in Utah, Partridge won the pole again, his fourth of the season. This time he was out front for five laps before Gilliland, who started on the front row, passed him. Gilliland and Herbst battled for the lead over the next 30 laps before Gragson passed both of them on the final lap.

“I just ran my race. Stayed focused, stayed positive,” Gragson said. “That’s really all I could do. Had a really good car, just one race on those tires. I’m really pumped up for my team, two in a row this weekend.”

Gragson won the second race with a 3.809-second margin of victory over Gilliland. Partridge was third, followed by Herbst in fourth and Todd Souza in fifth.

Ryan Partridge won the pole for both NASCAR K&N Pro Series West races at the Utah Motorsports Campus

“I thought I put my team back in a hole, messed up on a restart about halfway through running fifth,” Gragson said. “I was feeling down, but my crew chief told me that we were still in this thing, just really happy for these guys. Made my way back up and kept fighting till the end.”

Gilliland has a 13-point lead over Partridge in the K&N Pro Series West standings with two races to go. Gragson is 37 points behind Gilliland and in third place.

“It feels good,” Gragson said. “This is what we needed momentum wise. The guys worked really hard for it.”

The next K&N Pro Series West race is at Meridian Speedway in Idaho on Sept. 24.
