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.

This OEM replacement is a much more affordable option, saving you $150 or more compared to the Genuine BMW tensioner.

Hydraulic Belt Tensioner for E9x M3 with S65 engine and E60 M5, E63 M6 with S85 engine. This oil-filled tensioner keeps the main drive belt in the proper tension. Over time, the seals wear, allowing fluid to leak out and the tensioner then becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.

This is an OEM INA Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).
