K&N Performance Air Intake System (63-1050) Ford > Focus > ST250 💡 Why Choose ST CoiloversThe K&N AirCharger 63 1050 air intake system replaces the restrictive factory air filter and air intake housing in some Chevrolet Corvette Z06 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your Corvette Z06'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.
