Help increase your watercraft’s performance potential with high-quality marine products from K&N, which can help extend your engine’s working lifespan—and can also increase horsepower and performance. When using a poorly-designed air filter, contaminants can make their way into your engine and cause damage and premature wear. Furthermore, an inefficient oil filter can allow oil contaminants to build up within the engine, reducing its working lifespan. K&N performance filtration products are designed to keep contaminants where they belong—out of your engine—helping you enjoy your marine adventures for as long as possible.
