Tired of the hassle and mess of air filter grease? PC Racing’s Pro-Seal is the answer for a perfect filter to air box seal without the use of messy grease. The Pro Seal Air Filter Gasket is an added benefit to keep your intake clean and clear of those sneaky dirt particles. The typical air filter requires the use of filter rim grease to provide a seal, the Pro Seal Air Filter Gasket eliminates the need to use that messy grease. This neoprene gasket adheres to the rim (some applications do not have a rim) inside the motorcycle’s air box. The neoprene material creates a larger sealing surface and has memory for a perfect seal time after time. Due to the adhesives that are not affected by gas and oils, the Pro-Seal will not separate from the air box once installed. The Pro-Seal is available for most off-road motorcycles. .
