When having to replace valve cover grommets on the E6X M5/M6 S85 engine, BMW requires us to purchase new bolts. These bolts have grommets installed on them making it more costly to do a valve cover gasket job.

NRW have replicated the factory rubber grommet and make it out of silicone which has higher heat resistance of 170 degrees Celsius compared to the factory rubber grommet of 120 degrees Celsius. Each kit contains 34 grommets which covers both valve covers. 2 year warranty included.
