It is a fact of life that to get more efficient engine performance and to prevent oil leakage from blow-by, an engine's crankcase needs to be ventilated. Most modern vehicles utilize a positive crankcase ventilation (PCV) valve or some other form of emissions control system. Whereas for many custom built cars, a PCV valve may not be a practical design. Since the crankcase still needs ventilation, K&N has developed universal clamp-on crankcase vent filters.

These filters are ideal for engines, transmissions, even oil or gas tanks on racing vehicles that require venting. K&N has released 3 specific part numbers in different colors to offer a perfect match to a specific under the tank theme or vehicle paint job. 

These three conical vent filters are composed of a rubber base flange with an inside diameter of 1/2 inch. Included is a reducer to accomidate a 3/8 inch inside diameter. These come with a hose clamp and a chrome top.

All of these vent filters are made with a non-oiled, non-woven synthetic filter media to assist with capturing excess oil blow-by and provide a breathable filtration surface for escaping crankcase vent gases.
