This M6x16 mounting screw is used throughout the BMW model range on a variety of components. Most importantly, this is the latest updated version of the cam sprocket mounting bolt used in the E46 M3 S54 engine (and MZ3 and Z4 M). The original VAN0S-cam gear mounting bolts are known for weakness and a sheared bolt will quickly lead to VAN0S or terminal engine failure. 12 are required for S54 VAN0S bolt replacement (6 per cam sprocket). All other quantities vary based on application.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

Keeping tension on your timing chain is imperative for keeping your cams turning properly. If some slop develops in your chain because of a poor tensioner, the timing set can skip a tooth, causing catastrophic damage and potentially ruining your engine. These replacement can keep everything tight. The chain runs against this tensioner and keeps your chains tight on the cam gears and crank. It makes sure the no teeth are missed and your engine is running. Quiets loud chains.
