sayjac said:Most closely related to Napa Pro Select not Napa Gold/standard Wix.
Like most, if now not all NPS's, it uses the cheaper nitrile combo valve design. Pass.
I'll stick with separate adbv and metal bypass design.
The only difference is the ADBV, its the same filter media. Much better than a OCOD.
Actually the main difference is the bypass, rubber combo valve is a combined bypass and adbv in AEx and NPS. Napa Gold and Wix both use a separate metal bypass as well as a silicone, not nitrile, adbv.
Also Wix uses a synthetic fiber blend for media, I've seen no reference for AE noting it is the same as Wix or Napa Gold.
Also, media area may or my not be equal to the Wix. Youtube proves nothing regarding media type or area. As said, likely closer to Napa Pro Select.

Any pics or link regarding this statement? Afaik, NO standard Wix or Napa Gold canister has ever used a rubber combo valve design, nor is it advertised as such. The new Napa Silver advertises a combo valve design, but not the Napa Gold or Wix.
IMO, if the AE or NPS uses the cheapened combo valve design, then The Puro Classic and the Puro 'made fors' like Quaker State, Promotive of Group7 are a superior design with separate metal bypass.
Negative, I wish I still had the napa gold filters from 2009 but they had a silicone ADBV/combo that was silcone. Also look at pictures of WIX or Napa gold filters and compare the filter media to the AX, same thing.
Naked eye means little or nothing when it comes to filter/media efficency or media area. Most cellulose type media, blend or not, look similar, but efficiency can be very different. Also unless area is measured it to can be different Been shown here many times with Purolator Classic, P1's and the made fors like Quaker State and AAP Total Grip etc as shown here
As for your 09 Napa Gold "combo valve", not likely. Yes standard Wix/Napa Gold use a thread end bypass and silicone adbv, but they are separate, now and in 09. They are at thread end, but they are not combined in the nitrile combo valve design shown in the AE.
That said, if the AE works for you, great. I'll pass and use a filter with a separate adbv and bypass.
