Spark Plug Seal

NOK Corporation of Japan manufactures automotive and industrial sealing materials that include oil seals, o-rings, anti-seismic rubber, resins, gaskets, chemical composition and mechanical seals. The NOK seal is 2.5mm thicker than the OE Service seal but should fit this application with no additional modification. The difference in design provides a better seal than the OE Service part and is lower in cost. For those that prefer the OE Service-type seal, please order the NDK version.
