If not worried about color I bought some Warwick as they were made by WIX and were Wix Gold.
Have a small sticker that leaves tgem card blue.
Cost was $1.10 to $1.25 each on closeout.
PF-20
Are identical to the Wix and Wix Napa and Car Quest.
I bought all 3 brands and all 3 sizes.
I can get some numbers off them if need be.
I had a silly moment when I did so and still have 130 something filters in the 3 sizes. From closed auto stores.
And convention oil at 0.59 a quart. And. Buck for Mobile-1
