Product Details

This Bosal exhaust flange gasket is part of the BRExhaust Replacement Exhaust Gasket line, a direct-fit product family focused on OE-matched repair parts. The 256-109 gasket is used at common exhaust junctions such as the manifold-to-pipe, converter-to-pipe, and Y-pipe connections, where a precise seal is critical to controlling exhaust leaks and maintaining proper system operation. Applications include Honda Civic, Honda Accord, Acura TL, Acura RL, and other listed vehicles across model years from 1980 through 2007.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Exhaust leaks at a flange connection
