Description

Mr. Gasket Ultra-Seal gasket sets are made of a cellulose/nitrile material that is less compressible for excellent sealing and durability. This material has an anti-stick coating, plus a silicone bead around each intake port, except where noted, for a tight, leakproof seal. These gaskets are the perfect solution for intake-sealing problems associated with the small sealing areas between ports, and the different expansion rates of intake manifolds and cylinder heads. The choice of champions, these sets come complete with all necessary seals and can be trimmed to fit modified ports where needed.
