The K&N AirCharger 63-1050 air intake system replaces the 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 63-1050 air intake comes with a vented, carbon fiber topped K&N high-flow air filter that directs air into the custom molded intake for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.
