Timing Chain Tensioner, BMW - E36 M3 95, E30 M3 Upgrade

The original timing chain tensioner is the preferred complete tensioner assembly for older M engines that suffer from poor tension on cold starts.

This tensioner is original for S50 engines used in the 1995 M3. It is a direct replacement upgrade for E30 M3, E28 M5, E34 M5, and E24 M6. This tensioner is pre-assembled with the seals and tensioner spring and is 1,000 times easier to install than the original S14/S38 tensioner. The stiffer spring puts more tension on the chain guide for quieter and smoother cold starts (when oil pressure takes over).

This is a Genuine BMW S50 timing tensioner with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
