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.

Actually works on BMW!
I purchased this after the shorter black fluted tool I bought last year failed me. This thing is way better constructed, fits perfect , and actually works to turn it after you can’t turn it by hand any further. Was able to get torqued down to 25nm no problem finally with ease!
