The K&N 57-3090 FIPK air intake system replaces your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The 57-3090 air intake comes with a K&N high-flow air filter with a carbon fiber top and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered carbon fiber intake tube into the engine's throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor, air temperature sensor, evaporative canister vent line and other vent lines on certain vehicles. The oversized conical air filter can be used for up to 50,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points and requires commonly available tools. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.
