Worth it if you dont want your oil cap to get damaged.
Color: Black
I used to use a regular filter clamp form by oil filter cap and it was damaging it. I bought this and it was definitely worth it. If anyone is wondering I have a 2007 bmw 335i e93 and it was a perfect fit.

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).
