I am trying to get the air filter element for my 65 Cutlass, but it has been very frustrating. I ordered at Rockauto, Napa, etc and always I get something that does not fit on my original air filter pan. Does any one has any idea where to look for? Any part number to look?

 

I know this can be a headache. I go to the Wix filter site and use their filter look up; http://www.wixfilters.com/Lookup/App...aspx?Section=1
When I have their number any auto parts store can cross it to their number.
1 Air Filter 42097 V8 5.4L 330 CID 2 Bbl.
Air Filter 42081 V8 5.4L 330 CID 4 Bbl.
Fuel Filter 33050 V8 5.4L 330 CID
Oil Filter 51049 V8 5.4L 330 CID

The 42081 is same as an STP AF32
Rockauto sells the six filters.

Good luck,
Mike
