K&N 63 Series AirCharger Performance Intake Kit replaces the 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. This allows your vehicle’s engine to inhale a larger amount of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The filters on these kits are washable as well as reusable and are covered by K&N Million-Mile Limited Warranty.

Performance boost The K&N 63 series AirCharger for the 2012 Corvette Grand Sport was a perfect match for the OEM unit it replaced. There was definitely an improvement in acceleration and in engine sound. Low speed throttle response may have a fraction of a second delay but is definitely an improvement. Gas mileage also went up about 1.5 mpg. It shipped on time and arrived in perfect condition.
As advertised The filter installed easily. I noticed some increase in power at higher RPM’s which makes sense. Installed in a 2011 Grand Sport Vette.
