Question NAPA Gold vs. Purolator Air Filter - Opinions Please

Hi all

Just got back from a trip to the auto parts stores. Got a NAPA Gold air filter and then stopped at AAP for on-sale oil and found Purolators 25% off. So I got one of them too.

Man was I surprised at the difference. The NAPA looks a lot like a Fram and the Purolator looks like it's armored to do battle . Check out the picture and you'll see what I mean. I guess they both meet OEM standards so it really doesn't matter.

Any ideas why such a difference? Any experiences or opinions with either brand? Thanks.

I don't questions your findings, but I purchase the Purolator Pure One air filters and they look just like the top filter but with a black rubber surround. Maybe mine or yours is an old stock? Either way I buy the Pure One filters when they are on sale. I replace them often so I'm not worried about the small differences in design.

His is a "premium plus" That purolator looks REALLY nice, even better than the oem ones. Most filters I've seen look like the napa one though, even my amsoil reusable. How much was the purolator one before the discount?

The Purolator was $9.44 before the discount and is pretty close to the OEM that I replaced. Filter construction and the element itself seem to be almost identical.

The NAPA Gold must be outsourced from some other manufacturer since it looked a lot like the Fram I found at Walmart. It didn't fit as well either. The Purolator fit nice and tight like the original.

Nice, I think I may go for one of those purolators after my amsoil is done. The fit of that purolator looks great, I was kind of disappointed in the fit of my amsoil when I got it.

The napa is most likely a wix filter. The napa gold oil filters are made by wix. In the pic, the top filter (napa) looks like it has more pleats than the purolator. The aluminum/metal surround on the purolator is interesting; I haven't seen that before. I admit the purolator looks nice. A real question is how efficient the media is.

Another factor is how the filter seals in the filter housing. It seems to me that on a number of the aftermarket filters, the rubber gasket is thinner than the oem filter and doesn't seem to fit as snugly.

Here's a picture of the OEM filter with about 22K on it. Seems similar to the Purolator Plus. Sorry I didn't think to make a side by side photo and the wife's got the car.

I know NAPA Gold filters are usually made by WIX, but I also have a NG filter for my Civic and the media is not the same at the media in the NG for the Forester. WIX has kind of a fuzzy finish to it and the NG for the Forester did not. It only said "NAPA Gold Made in USA" on it. No mention of WIX or Gastonia NC where I think WIX makes filters. Doesn't really matter...it didn't fit nearly as well as the Puro so it got returned.

Is a filter made by Wix a good thing or a bad thing?

Wix is one of my favorite brands, I think they make quality stuff. Typically they make stuff for NAPA I thought.

Wix filters should be quality. Maybe they have more than one type of oil filter media or changed medias at some point or something. They guy at carquest said their filters are made by wix too.
