Doctor's Best D-Ribose is a unique 5-carbon carbohydrate that is a fundamental building block of ATP (adenosine triphosphate), the source for all cellular energy. Ribose is the starting point and rate limiting compound in the synthesis of these fundamental cellular compounds and the availability of ribose determines the rate at which they can be made by our cells and tissues. Studies have shown that ribose supplementation can enhance cardiac energy levels and support cardiovascular metabolism. Further studies suggest that ribose plays a role in supporting muscle energy recovery after exercise. Exercise increases free radical production in muscle tissue. Ribose may strengthen and support the body’s crucial antioxidant defenses.GRP:GRNSHP_3

Works perfect for BMW S63 engine.
I used this to change the oil on my BMW M8 with the S63 engine. It was a perfect fit. It extended far enough onto the filter housing to be quite secure with no risk of slipping off and stripping the housing. It was snug on the housing and did not bind up due to having a loose fit. The tool feels well-built and I suspect it will outlive me given my occasional personal use. It would still probably hold up well even for daily shop use as long as it was not abused (repeatedly dropped, slammed around, etc).
