Valve cover gaskets for the serious engine tuner. German made OEM valve cover gaskets are your assurance of tight, no leak valve adjustment jobs. They are manufactured from the same cork and rubber formula that was originally developed for Volkswagen. They are packaged in sets of 25, just as we receive them from overseas. They fit all 40hp, 1300, 1500 and 1600 based engines using stock valve cover gaskets.
