GLM 34430, Evinrude/Johnson 321794, and Mallory 9-60418 are interchangeable with the Sierra 18-0989 Air Silencer Gasket. The Gasket Air silencer is to seal the tiny space between the two assembled portions of the silencer, an exhaust system component designed to reduce noise from the carburetor intake port. It also prevents hot exhaust gasses from entering the automobile and maintains proper system pressure; if it fails the engine's performance would be jeopardized. 100% NEW and constructed with the highest quality components available. Computer-assisted quality control and unparalleled dependability.
