“After the install that went perfectly, thanks to great instructions and the video from the K&N web site, I am amazed at the results. Throttle response is amazing and I use less throttle to get moving. Also, my truck does not down shift anymore climbing hills with the cruise on.” – Michael from Oklahoma [Part No. 77-3070KP]

WHY CHOOSE A K&N PERFORMANCE AIR INTAKE SYSTEM?

The 77-1578KP is designed to help provide a smooth, low-restriction path for airflow to the engine. Your engine needs oxygen to create power; the cylinders in your vehicle’s engine need to have air to create the explosion that produces horsepower and torque. Allowing a higher volume of air into the cylinders allows the engine to burn fuel more efficiently during combustion—providing an increase in power.

“Easy to install, noticeable power increase.” – Floyd from North Dakota [Part No. 77-2581KP]

A performance air filter helps protect your engine from contaminants

ALUMINUM INTAKE TUBE INCREASES AIRFLOW

The K&N® 77-1578KP air intake system is a free-flowing, mandrel-bent polished aluminum tube cold air intake system designed to replace the factory air filter and air intake components. The 77-1578KP also incorporates a steel heat shield, which helps protect the air filter and intake air from high temperatures within the engine bay.

“Easy to install, sounds and feels great when accelerating. Very happy with the results. Recommend this to anybody looking for a easy first upgrade for their vehicle.” – Eric from Washington [Part No. 69-1210TS]

IMPROVE ENGINE SOUND

Factory intake systems often feature intake tubing with tight bends, baffles, and other obstacles that can slow airflow and muffle engine noise. K&N intake systems are designed to give your engine a more satisfying growl on acceleration, but return to quiet once at speed.

HIGH-FLOW AIR FILTER™ OFFERS EXCEPTIONAL PROTECTION

The High-Flow Air Filter™ included in the 77-1578KP intake kit is oversized with a conical shape, providing a greater surface area and allowing for a service interval of up to 100,000 miles between cleanings (under normal highway driving conditions). High-Flow Air Filters feature an oiled, layered design—providing up to 50% more airflow than a traditional paper filter. When your filter does need to be cleaned, you can use the K&N Recharger® Kit (99-5000 or 99-5050) to quickly and easily restore your filter’s performance. Each K&N intake (and filter!) is designed to last for the life of your vehicle.

INSTALLATION

The K&N 77-1578KP intake system is engineered to incorporate factory mounting points and the factory mass air sensor. Installation can typically be completed in 90 minutes or less, and requires only simple hand tools. Detailed instructions are included in your kit.

WARRANTY

Each intake system comes with a 10-Year/Million Mile Limited Warranty.
