Valve Cover Gaskets

From the factory, BMW S65 valve cover bolts feature integrated non-serviceable grommets. These rubber seals tend to weaken, becoming brittle after years of heat and oil exposure. Replacing these bolts and integrated grommets can total over $280

To address this issue, NRW has developed a solution: a silicone replica of the factory rubber grommet, boasting a superior heat resistance of 170 degrees Celsius compared to the original's 120 degrees Celsius. Each kit contains 26 grommets, enough to service both valve covers.
