2016 Honda HR-V 1.8L models can be easily upgraded with enhanced performance and lower maintenance for several years with a reusable K&N replacement air filter, number 33-5037

In a stark contrast to the SUV marketplace of the early 2000’s, automakers are now developing smaller, lighter, and more efficient crossover utility vehicles (CUV) in an effort to improve fuel mileage. The Honda Motor Co., Ltd, a company already known for building fuel efficient vehicles, has released the 2016 Honda HR-V 1.8L as its smallest North American market CUV offering. The 2016 HR-V shares the same platform as the third-generation Honda Fit. The release of the 2016 HR-V allows the Honda Motor Co., Ltd to offer three size choices in CUV models; starting with the HR-V, the Civic-based CR-V, and finally the Accord-based Honda Pilot.

The 2016 Honda HR-V shares its 1.8L R18A1 inline-four cylinder engine with the 2006+ JDM & North American market Honda Civic. While 1.8L R18A1 SOHC VTEC engine provides reasonable performance, considering it is tuned to maximize miles per gallon, a K&N high-flow replacement air filter could help with better throttle response and quicker acceleration. A K&N high-flow replacement air filter is different from the factory or standard replacement air filter in that K&N uses cotton gauze filter media woven to exacting specifications. Cotton, by nature, is more breathable than the paper or sometimes foam media used in most automotive air filters.

The ability to get more air into an engine with less energy wasted on drawing in air allows an engine to work more efficiently and can result in improved performance, quicker acceleration, and better throttle response. Additionally, K&N’s in-house air filter filtration efficiency testing, following the ISO 5011 protocol, ensures that K&N replacement air filters provide increased airflow without sacrificing engine protection. Following this internationally recognized testing protocol, K&N replacement air filter 33-5037 was shown to provide a 98.70% overall filtration efficiency rating.

The 2016 Honda HR-V 1.8L K&N replacement air filter is designed to install just like the factory air filter and without any need for modifications or fuel management changes

Besides enhanced performance, a K&N replacement air filter offers years of reusability. The cotton air filter media and sturdy construction of K&N replacement air filters allow them to be washed and reused time and again. The high-flow nature and pleated design of a K&N replacement air filter allows them to go up to 50,000 mile before cleaning is needed, depending on driving conditions. This means the average owner could go about 4 years before the air filter needs attention. When it’s time, K&N air filter cleaning can be easily performed using a readily available K&N Recharger air filter service kit.

Most K&N replacement air filters are designed to install just like the factory air filter and without any need for modifications or fuel management changes. Plus K&N air filters are backed by a 10-year/million mile limited warranty and will pay for themselves over time.

Owners of 2011, 2012, or 2013 Buick Regal CXL Turbo or GS models wanting more performance, can bolt on a K&N air intake for an immediately noticeable increase in power

Buick is currently the oldest active American auto maker and the marque has always been intended as more upscale than Chevrolet, Pontiac, or Oldsmobile, but reasonably priced compared to the flagship Cadillac brand. As such when the Buick Regal was introduced in 1973 it was intended as an upscale mid-size car. There wasn’t much that set the Buick Regal apart from its GM counterparts until the introduction of the second generation Regal in 1978. In 1978 the Buick Regal could be equipped with a 3.8L Turbocharged V6 engine at a time when only European imports, like Mercedes, Porsche, or Saab, offered turbocharged power.

Based on the Opel Insignia Epsilon II platform the 2011, 2012, & 2013 Regal CXL Turbo came equipped with a turbocharged 2.0L direct-injected Ecotec DOHC I4 rated at 220 horsepower

The facelifted second gen Buick Regal became competitive on the 1981 NASCAR racing circuit and Richard Petty drove a Regal to victory in the 1981 Daytona 500. The Regal won a majority of the 1981 and 1982 NASCAR races and took the NASCAR manufacturers title both years. Buick capitalized on its NASCAR success and in 1982, the Regal Grand National, named for the NASCAR Winston Cup Grand National Series, made its debut.

The Buick Regal Grand National, and the final year 1987 Limited Production Buick GNX "Grand National Experimental", were able to best the Chevy Camaro on the dragstrip making the Grand National an instant legend. Hoping to grab the attention of younger performance minded buyers who might otherwise opt for an upscale European car, Buick brought back the Turbo Regal in 2011 and it was also the first Buick model in 22 years to be offered with a manual transmission.

K&N Buick Regal Turbo air intake system 69-4532TTK will fit an function as if designed by the factory on 2011, 2012, or 2013 Buick Regal CXL Turbo or Buick Regal GS models

Based on the Opel Insignia Epsilon II platform the 2011, 2012, & 2013 Regal CXL Turbo came equipped with a turbocharged 2.0L direct-injected Ecotec DOHC I4 rated at 220 horsepower. The more performance oriented Buick Regal GS came with a GS-only high-output version of the Ecotec 2.0L turbo engine boasting 270 HP. Owners of 2011, 2012, or 2013 Buick Regal CXL Turbo models looking to get closer to the performance of a Regal GS, or a GS owner wanting even more performance, can bolt on a K&N performance air intake for increases in power than will be immediately noticed.

A K&N air intake system is designed to increase airflow, reduce restriction, and nearly eliminate turbulent airflow as it enters a vehicle’s throttle body. Reducing the amount of effort needed to overcome air intake tract restriction can directly translate to increased power at the wheels. K&N air intakes often produce greater increases in performance on turbocharged engines. The 2011, 2012, or 2013 Buick Regal CXL Turbo or Buick Regal GS turbocharged 2.0L direct-injected Ecotec DOHC I4 engine is no exception.

K&N Typhoon air intake 69-4532TTK demonstrated a maximum estimated increase of 15.93 horsepower and 17.12 lb-ft of torque at 4,887 RPM over the factory intake design

By replacing the restrictive 2011-2013 Buick Regal Turbo air box with a high-flow reusable K&N air filter and swapping the accordion intake ducting for a mandrel-bent aluminum intake tube, K&N Typhoon air intake 69-4532TTK showed exceptional performance increases on K&N’s in-house dynamometer. This air intake system demonstrated a maximum estimated increase of 15.93 horsepower and 17.12 lb-ft of torque at 4,887 RPM over the factory intake design of a 2013 Buick Regal 2.0 turbo. This Regal air intake system does more than just provide more power, as it will also improve drivability by reducing restriction; allowing the turbocharger and engine to work more efficiently.

K&N has stepped in to offer a street legal bolt on performance upgrade that can be installed in less than 90 minutes and with basic hand tools on 2014-2015 Toyota Tundra V8 trucks

K&N engineers retained the 2014-2015 Toyota Tundra 4.6L or 5.7L V8 stock air filter box allowing K&N intake 57-9036 to earn an exemption order from the California Air Resources Board

Toyota took on the first gen Tundra's critics by introducing a larger second generation Toyota Tundra for the 2007 model year. The second generation effectively squashed complaints about the Tundra being small, but the second blow came from Toyota with the introduction of an all-new 5.7L 3UR-FE V8 engine. The dual VVT-i 5.7L V8 engine was rated at a whopping 381 horsepower and 401 lb-ft of torque. In 2010 Toyota replaced the 4.7L I-Force V8, first introduced in the 2000 Toyota Tundra, with a 4.6L 1UR-FE V8 engine originally used in Lexus models in the Middle East. This new smaller engine belongs to the same engine family as the Tundra's 5.7L engine. It shares the 5.7L engine's 94 mm bore, but with a shorter stroke.

The 381 horsepower and 401 lb-ft of torque offered by the second generation Toyota Tundra's 5.7L 3UR-FE V8 is probably more than enough power for most situations. However, there are times such as towing, hauling a fully loaded bed, or even off-roading where a boost in horsepower can come in handy. For 2014-2015 Toyota Tundra 5.7L V8 owners in need of more power, or 2014-2015 4.6L V8 owners looking to close the power gap, K&N has stepped in to offer a bolt on performance upgrade that can be installed in less than 90 minutes and with basic hand tools for both V8 engines.

The second generation Tundra effectively squashed complaints about the Toyota Tundra being small, but the second blow came from Toyota with the introduction of the 5.7L 3UR-FE V8 engine

When tested on K&N's dyno, this air intake produced an estimated additional 5.8 horsepower and 5.73 pound-feet of torque over the stock system of an otherwise stock 2015 Toyota Tundra 5.7L V8

The K&N 57-9036 performance air intake system is a little different from the average K&N cold air intake system. K&N engineers chose to retain the use of the 2014-2015 Toyota Tundra 4.6L or 5.7L V8 stock air filter box when designing this K&N performance air intake system. Retaining the use of the stock air box allowed K&N engineers to increase performance while leaving all the stock emissions control equipment in place. This allowed K&N air intake 57-9036 to earn an exemption order (EO) from the California Air Resources Board (CARB) for the 2014-2015 Toyota Tundra models listed below.

Despite appearances, the K&N 50-state street legal air intake system for 2014-2015 Toyota Tundra 4.6L or 5.7L V8 pickups is precision-engineered to provide a guaranteed increase in horsepower, better acceleration, and improved engine sound. When tested on K&N's in-house dyno, this air intake produced an estimated additional 5.8 horsepower at 5,508 rpm and 5.73 pound-feet of torque at 3,796 rpm over the stock system of an otherwise stock 2015 Toyota Tundra 5.7L V8. Similar results can be expected when this street legal air intake is installed on 2014-2015 models with a 4.6L V8 engine.

Street legal performance air intake 57-9036 is designed to fit and function properly on the 2014-2015 Toyota Tundra models listed below:

2015 TOYOTA TUNDRA 5.7L V8 F/I - All CARB EO Number: D-269-52
