Perfect for Volvo
This tool was perfect for removing the oil filter of my 2005 Volvo V70. It does what it’s supposed to do and was cheaper than the others. Very satisfied with this purchase.

Fits 05xc70 oil filter
It’s alright. Does get stuck on the filter housing. Had to pry it off with a pry bar after I was done. But it did work
