Protect critical systems
When using a poorly-designed disposable air filter, dust, dirt, and contaminants can make their way into your engine—causing damage and premature wear. In addition, an inefficient oil filter can allow oil contaminants to build up within the engine, reducing its working lifespan. K&N performance protection products are designed to keep contaminants where they belong—out of your engine.
