Are K&N Air Filters Worth The Money?

K&N E-3333 Air Filter

The K&N 57-1542 FIPK air intake system replaces 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. 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.
