I was in auto zone today and noticed they have STP oil filters in a gold box they say extended life 99% efficiency @20 microns per iso 4548-12 optimized for synthetic and conventional motor oil. Engineered to last 10,000 miles. Also looks to have a silicone anti drain back valve.. They look to be made by purolater but looking inside on the center tube there are a lot of oil holes and they are of good size not those restrictive looking tiny slits purolater is using on their new line. Although i did not cut any of them opened upon first glances they look like a nice filter.. I don't remember what the cost was but it was in the $8.00 range i think.

Cool, thanks for the heads up. Nice to see an effieciency rating. If they are made by Purolater I wish they would do the same with the BOSS.

There was a post about a month back about them. Made in Korea, not a Purolator product.

Thought you were gonna be the 1st to cut open filters in the store - LoL.

I posted about them in August, I also posted a cut open un used one in another thread I was un impressed with the machining there were burrs on all the inlet holes and some possible sealing issues with the adbv against the base plate. Overpriced midrange Korean junk if you want my 2 cents.

I am getting set to cut a variety of filters that would compete with Purolator Classic, Purolator PureOne and Motorcraft. I think Champion Labs makes some reasonable product that at least does not tear. I am also thinking the eCore designs have been improved.

No it's not synthetic microglass media, they are using tons of pleats to achieve the "10,000" mile rating which means it's cheap media a form of cellulose possibly resin impregnated or minimal glass fibers, I can't know for sure.
Also the anti drain back valve is very flimsy in the STP compared to any other silicone valve I've held
They looked a little like puro's except the center tube looked like it had a lot of nice oil holes instead of those tiny slits puro uses in their new filters. Now i see the media in these filters and it doesnt have wavvvy media so i guess it can't be..
Wow if they are machined like that with those burrs this is yet another filter i won't be buying.
If they are made in China someone should tell them lots of people cut open filters these days so they can't hide anymore.

The only Korean oil filters I'd buy are OEM Hyundai/Kia
Other than the high price and issues with machining its an okay filter, but still the media is nothing fancy so i would be interesting to see how it ACTUALLY held up to a real 10k run. It would be competitive at about $6.
They claim a 20 micron rating on the box
I bet they sell a tons, thousands nationwide, of them every day. I don't know why AZ needs to choose filters made in Korea when there are USA brands for the same price that are better. I guess they don't need to, but maybe there is something going on behind the scenes? I mean, they are an American outfit selling in America, right? maybe the profit margin on the Korean filters sold for $9 is super high compared to a USA made filter.

Been using the OEM filters for my Hyundai daily driver - I see no reason to go anything else as they are good quality. Just watch out for the fakes that are out there.

South Korea isn't part of China. It's printed on the box & label where these filters are made.
You liked the Driveworks Made in China filters at one time except having "Made in China" on the filter made your shop "look bad" in your opinion.

I said "if" they are made in China..
As for the Driveworks filters they seemed ok but the Wix filters look better on a quality rebuilt engine and the Wix made me feel better. I also used Motorcraft on the ford engines. And once in a while Mopar on the Mopars but changed most of that because some of those filters were made by puro and i did not want them on any of my engines.
