I bought this sturdier Oil Filter Wrench when I was having trouble removing the oil filter on my 2003 BMW 1150RT with a stamped steel oil filter wrench that I had previously used. It still slipped, but adding a strip of grit mesh between the filter and the filter wrench saved the day. I still like this cast aluminum filter wrench better than the stamped steel one.

Does not fit Chevy LS3. Too big.

Color: Silver

Does not fit 2014-17 Chevrolet SS (LS3 V8) genuine GM oil filter. It slips. It's supposed to measure 74 mm flute to flute, but actually measured 77 mm with calipers. This wrench looks like it was used and was re-packaged with office tape. I purchased correct size from dealer that fits perfectly.
