Up on the workbench today is a Premium Guard PG4476, which Premium Guard lists as a cross for Toyota 90915-YZZN1. I am cutting a slew of filters to compare to the Wix WL10332 that I was thoroughly disappointed with for a variety of reasons, but primarily, poorly formed louvers.

The Premium Guard PG4476 is 3 1/8 in tall which taller than the Toyota 90915-YZZN1 and the Wix WL10332 by 1/2" on the Wix and 7/16" over the Toyota.

The can feels heavy, and the box is labeled MADE IN CHINA, Overall the filter weighs 217.3 g. Baseplate has 8 punched holes with no evidence of any burrs on the ADBV side, the baseplate weighed 91.9 g. Can thickness was 0.0195 in thick. The ADBV is black likely nitrile. The filter is constructed with the bypass valve located in the dome end, the valve is constructed of a 0.0550 in thick stepped rubber disc sealing on metal with no visible light leaks. The BV opening is 5/16" in diameter. The filter core weighed 66.2 g, was 2 3/16 in tall, had 46 pleats, with a media length of 44 in, and a media thickness of 0.0290 in and used a metal crimped seam. The media is supported on each end by a metal end cap with no light leaks noted at the potting material, and no glue residue was present on the endcaps or elsewhere in the filter media, slight potting material squeeze out into the pleats as shown. The center tube uses a spiral wound crimped seam perforated tube with well formed holes that were all even with no burrs noted. The core of the filter is supported by a leaf spring that felt relatively weak compared to other examples I've cut in this size.

Overall, this seems like a decently built filter, and not a bad price point. Although, for me, I prefer a filter not from this COO if I can help it. Enjoy the pics.

Nice touch ... don't see a rubber disk for the bypass valve much, pretty rare. Good to ensure a leak free seal.

Look like a coil spring to me.
 
Same here. That being said, I will buy a Premium Guard made filter or just about any other China/Asian made filter over the junk Purolator and FRAM are putting out on a regular basis.
Same here. It does give me some comfort knowing PG is a US based company with filters made overseas vs a US company owned by a overseas company.
 
There is a clear difference between a manufacturing plant with US employees, and an office which distributes what they buy from a factory in China. Also a difference between Germany and China at this point in time. Even S Korea versus China.

There’s a very clear difference in quality/quality control between a US made filter vs overseas made filter(which is unfortunate). US pride in craftsmanship is at an all time low.

Well that’s up to the supervisor. I would imagine in China you are expected not to make a mistake and you better not lift your head all day to see the clock. I wouldn’t want to be a worker in China. But it looks like half the things I buy are made there.
Well fifteen years ago it may have been half.

In the passenger car filter space, yes. Not in the HD space. The Fleetguard and Donaldson filters generally look excellent.
 
US management is lazy and doesn't focus on real company problems ... too busy playing golf and drinking at the golf course club house, lol. And they expect to get paid insane wages for holding their company position. Seems like a lot of the problems being seen with US oil filter brands these days is manufacturing quality. That points to the people managing the factory production and quality assurance not doing their job very well. If the manufacturing engineers and the factory workers can't meet the expected manufacturing quality, then find workers that can.

Yes. I should have said US M+H and First Brand pride is at an all time low. I need to explore more Fleetguard and Donaldson filters for passenger cars.

I wouldn't be so sure about those guesses as many of the Asian factories put up regular footage of their work environment and they look pretty decent to me with employees looking around freely and moving at a casual pace where as the U.S companies DO NOT put up any regular footage except maybe like 8 years ago and honestly who knows who is in these U.S. factories in 2025. I would wager the factory floor is NOT full of Americans.

I play drums and am a geek about those products and the China factories are far and away nicer than the U.S facilities which are easily the ones that are more like sweat shops. Plus the drums are generally higher quality from China and Taiwan as well.
 
This makes me feel better about the 2 dozen part plus/pg filters I’ve got in the garage. I don’t run my oil changes long enough to worry about not having a silicone adbv but the pics here look like these filter could run 10k if needed.
