The K&N 57-3094 FIPK Generation II air intake system replaces the restrictive factory air filter and air intake tubing while retaining the factory air box on select Chevrolet Camaro and Cadillac CTS with V6 3.6L engines. K&N air intakes are designed to dramatically reduce air intake restriction as they smooth and straighten air flow for a guaranteed horsepower gain. This allows your engine to inhale a larger amount of air than the factory air filter and air intake assembly. More air means more usable power and acceleration throughout the engine's RPM range. This air intake comes with a replacement K&N high-flow air filter and an aerodynamically engineered air intake tube that easily connects to your vehicle's factory air box and throttle body. The factory crank case vent tube, and EVAP hose installs into the K&N intake tube. The air filter can be used for up to 50,000 miles before servicing is needed depending on driving conditions. This air intake system is designed for quick and easy installation with commonly available tools.
