K&N RU-5176 Universal Rubber Air Filter - Washable & Reusable High Flow Air Filter For Racing, Generators, ATVs

If you need a solid air filter that fits a bunch of different engines, this K&N universal one is a great pick. It's made with a flexible rubber flange that can stretch up to 1/16 inch to fit in-between sizes—super handy if your intake isn't exactly standard. The design boosts airflow for better horsepower and acceleration, and it filters out dirt without choking your engine. You can use it on race cars, generators, snowmobiles, tractors, even RC cars. Best part? It's washable and reusable, so you just clean and re-oil it instead of buying new filters all the time. The rubber absorbs vibration and clamps on securely. Hundreds of sizes available, but this one's a popular universal option. Saves money in the long run and keeps your engine breathing easy.
