I had looked everywhere for an oil filter wrench that would fit the cartridge filter on this1999 Volvo v90 XC AWD. Nothing local worked and then there was the issue where the recommended filter wrench slipped. When I was ordering the 86.6mm wrench, I looked at the pictures and noticed it said if I had a specific type of marking on the housing then I would need this 86.4mm wrench instead. Thanks to that bit of info I can now replace the filter. Works 100% like a charm and filter was easy to remove with a standard ratchet. Wrench seems well made and the price was perfect, especially compared to some of the others that are $35+. Very satisfied with this purchase.

Money Saver!!!!

Purchased yesterday and put bot cans in my gas tank. Very pleased with how it works. Had a code P0175 02 sensor bank 2. Thought I had to replace the sensors but looked into products and read the reviews of these can. Check engine light went off this morning. Drove it aggressively after I used the cans and they worked as advertised. Highly recommend.

car performance improvement

I bought this to use in my 2021 chevrolet equinox when my check engine light came on with an exhaust issue. so far I believe it's working. I have noticed increased mileage and a little more "zip" in the engine.
