Reusable after wash, I'd recommend K%26N wash and oil spray kits that perfect combination forever.

5 Star Review

Perfect fit, great performance, engine smoothed out and rumbles nicely now. Super fast shipping, too! 2002 Avalanche 2500 with 8.1 litre 496 cid motor and air cooler after market intake assembly, chipped, variable fuel and power control, towing beast, fully loaded every option, goes anywhere in comfort and style.
