Good quality and price
This fits the original cover that was on my car. Made the removal of the oil filter cap very easy effortless.

not tight enough
It did slip on my BMW M5 F90 oil filter — it wasn’t tight enough. I had to use a microfiber cloth to fill the gap and make it tighter in order to loosen the oil filter.

Works as promised
Size: 2-Pack
Great product! Highly recommend. My check engine light turned off quickly, probably less than 20 minutes after I added the bottle to my tank and started driving. I waited a week to write the review just to make sure the check engine light didn’t turn on again. Success!
