completely replace the factory air intake assembly with an aerodynamically engineered tube and an oversized conical air filter. With a K&N Performance Air Intake System, consumers can count on increased acceleration and horsepower whether towing a toy hauler trailer, or heading to the job site.
This air intake system uses a conical shaped chrome top high-flow air filter (

The result is a high-flow air filter that captures harmful particles, provides a large surface area, and has a long service life. This K&N air filter performs for up to 100,000 miles before service is required, depending on driving conditions.
Improving the air path between the filter and the engine is the black powder coated, mandrel bent aluminum intake tube. Our black powder coated aluminum intake tubes offer power and a stock appearance.
