Product Style: 63 Series Aircharger Kits Estimated Horsepower Gain: 10.48 HP @ 5445 RPM A sister product to our 57 Series FIPK, our 63 Series AirCharger® Intake Kits are guaranteed to increase horsepower and come with a Million Mile Limited Warranty. K&N intake systems replace 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.

The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available
