I m curious as to which size cap wrench i need for the 2.3 canister filter, some say 76mm with 14flutes, some say 75.6 with 14 flutes...i can't imagine how much difference .4mm could make? I did the first oil change with a 76mm wrench that was a 76/74mm...the depth of it i think was at fault of the minor slippage. I have since picked up an A251 from pep boys to see if that works better on the next oil change. But prices for the mazda filter is ridiculous plus shipping, I tried to get my local dealership to get it for me but they claim they can't find the listing even though i gave them the aks75150 number. Also, trussville mazda sells the aks75150 while mazdastuff sells the aks75140...once again whats the deal with the size?

 

you need strong hands, and when putting it back on , dont over tighten...that's why I HATE taking my car in for an oil change, they always put them on too tight
