57-5505Guaranteed to increase horsepowerDesigned to improve throttle response and engine soundLasts up to 100,000 miles before service is required (depending on driving conditions)Easy to install, usually in 90 minutes or lessFree-flowing high density polyethylene tubeThe K&N 57-5505 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Mitsubishi Eclipse models. 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 57-5505 air intake comes with a chrome topped K&N high-flow air filter that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine�s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hose. The oversized oval shaped air filter comes with a water repellent DryCharger filter wrap to protect the filter from moisture. The air filter 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 existing factory mounting points. The tools needed are a screwdriver, needle nose pliers, ratchet set and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.
