PERFECT FIX

Perfect fit for DIY oil filter change on 2021 BMW X-7. Good quality, well made, should outlast the vehicle.

I like the red. It does the intended job perhaps like others do.
Size: 32 mm, Color: Red
It's a socket. It does the job without any fail to report. I like that it's red so that I find it easily in my tool chest the next time I need it.
