Stock 390 Air Filter

[pchelp101]

Can anyone give me the correct PN for the OEM air filter on my 390 ? I searched online and came up with the Fram CA324A, it has the correct diameter but its about 3/8 in too tall.

Go to NAPA online and search for the filter for your vehicle-a bunch will come up. You can click on each one and see the measurements for each dimension.

Never heard of Wix, do you get your filters from them?

I have used many filters made by Wix, but never Wix-branded filters. Perhaps you have too. Confused yet?

Wix manufactures NAPA-branded filters. They also market filters under their own name. They make filters for a wide variety of vehicles and industrial applications.

I have used NAPA-branded filters for many years without any troubles. I generally use "gold" ones on modern vehicles and the cheaper ones on the old trucks. Napa sells them at three price points: gold, silver, and pro select. I suspect that the lowest priced "pro select" units are comparable to FRAM, STP and Purolator filters commonly found in discount stores.

If my memory is correct, the NAPA part numbers for filters are based on the Wix part numbers, so you can cross-reference them. I have never seen Wix-branded filters in stores in my area, only online, and when I factored in convenience and shipping charges, NAPA-brand filters were a better deal for me. Wix or NAPA, you can't go wrong.
