The K&N 57-7000 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Porsche 911 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Porsche 911's 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 57-7000 air intake comes with a light-weight carbon fiber topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed from the fresh air supply duct, past the air filter and through an aerodynamically engineered intake tube into the engine's throttle body for a guaranteed power gain. The oversized cone-shaped air filter is wrapped with a water repellant Drycharger filter wrap that can be used for up to 100,000 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.
