Genuine BMW S65 V8 Timing Chain Tensioner (Sold Individually)
Part Number: 11317839053
Condition: Brand New, Genuine OEM
Restore the precision and performance of your BMW’s high-revving heart. This is a Genuine BMW replacement timing chain tensioner specifically designed for the S65 4.0L V8 engine found in the E9X M3.
Over time, hydraulic tensioners can lose their ability to maintain consistent pressure, leading to "chain slap," increased wear on the timing guides, or—in extreme cases—skipped timing. Using a genuine factory part ensures the hydraulic damping rates match your engine’s original specifications.

Longevity: Protects your expensive timing guides from premature wear caused by a slack chain.
Installation Notes
Pro Tip: While these are sold individually, it is highly recommended to replace both tensioners at the same time to ensure equalized chain tension across both cylinder banks. Always use a new crush washer/seal when installing to prevent oil leaks at the tensioner port.
