PC Racing Pro-Seal Air Filter Gasket PC3 — Yamaha YZ125 / YZ250 / YZ250F / YZ450F / Suzuki RMZ250 / RMZ450 1993-2022

Product Description

Ditch the grease gun and secure your engine with the PC Racing Pro-Seal Air Filter Gasket. For years, the only way to guarantee a perfect dust seal between your air filter rim and the internal airbox lip was applying a messy layer of heavy grease. The Pro-Seal completely eliminates that hassle. It provides an airtight, track-proven barrier that prevents catastrophic dirt, sand, and fine dust particles from slipping past your filter and scoring your cylinder wall.

Manufactured from premium, heavy-duty neoprene material, this application-specific rim gasket features a specialized, high-tack adhesive backing. Formulated to resist degradation from high-octane race gas, harsh chemical air filter oils, and aggressive spray solvents, the gasket stays permanently bonded to the airbox sealing surface. This simple modification turns filter changes into a quick, clean, and completely reliable process, keeping your intake tract pristine.

Frequently Asked Questions

Q: Does the gasket attach to the foam air filter itself or the airbox?
A: The Pro-Seal features a specialized adhesive layer that mounts permanently inside your bike's plastic airbox structure along the rim where the filter seals. It stays inside the airbox when you remove the filter to clean it.

Q: Will spray cleaners like contact cleaner or filter cleaner melt the adhesive?
A: No, the advanced adhesive compound is engineered specifically to withstand repeated exposures to pump fuel, race fuels, spray oils, and standard air filter detergents without lifting or releasing.

Q: Do I still need to use rim grease on my foam filter after installing this?
A: Not at all! That is the primary benefit of the Pro-Seal. The high-density neoprene material creates a reliable compression seal against the foam filter flange, allowing for a completely grease-free seal.

Expert Pro-Tip: Before applying the adhesive side of your new Pro-Seal to your airbox, preparation is absolute king. Clean the plastic mounting flange multiple times using contact cleaner or isopropyl alcohol on a clean microfiber towel until there is zero oily residue or old filter grease left behind. Letting the adhesive cure against a 100% clean, dry surface ensures a permanent bond that will last for years.
