Great Value...Great Fit....Works Great!
For the money, this is a great value, and if used properly, should last as long as your N55 engine....the construction material may cause it to distort, and may be difficult to separate from the filter assembly, but if this occurs, the cap was installed too tight or it's being installed too tightly...cranking on the plastic oil filter canister lid without disregard to propr torque value will result in needing a new filter canister lid and/or tool.....I'd buy this product and same mfg products....

Not a bad oil filter wrench, actually!
Lots of hit or miss reviews here, but for me, it fits like a glove and easily allows me to apply the 25-26 Nm of torque needed to open or close my BMW oil filter cover (2020 M4 but most BMWs use the same type of filter cover). It does get on there pretty tight and might be hard to remove. Solutions: - wait for the engine to cool down a bit, and it will come right off - use a pick tool to loosen it

Great value and Perfect Fit
This little oil filter wrench fit my BMW M340i perfectly and made the job a breeze. It locked onto the cap snugly, with no slipping or wobbling, and let me remove and reinstall with confidence. The material feels sturdy for the price and if you use the proper torque instead of cranking down on the housing, it should last a long time. Highly recommend for DIY oil changes.
