K&N Intake Systems completely replace the restrictive factory air intake assembly with an aerodynamically engineered tube and an oversized conical air filter. Most systems come with a heat shield to isolate cool air taken in by the engine. They take about 90 minutes to install and deliver huge increases in power and acceleration that you will feel on your next drive. Offfering up to 4 times more horsepower than from a K&N air filter alone, these are the systems that will make it seem like you have a different car!
