Timing Chain Tensioner Piston, BMW - E30 M3, E28 M5, E34 M5, E24 M6

This is the timing chain tensioner Housing and Piston - without the spring - for S14 and S38 engines. This is just the piston and housing to replace a worn tensioner piston. The internal spring is sold separately.

The 95 M3 tensioner uses a stiffer spring and can be used as a direct replacement/upgrade, without the need to rebuild the tensioner or force the S14 spring into the housing.

This is a Genuine BMW chain tensioner piston 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.
