Today I changed oil in my '05 GXP and decided to disect the old Pure One PL14006. Then I decided it wouldn't do any good to compare it to itself so I dissected a brand new PF46 and 51042 in the name of science.
Media:
- Wix: 1.5" X 60" = 90 sq inches. Pleats are 3/4" wide
- Pure One: 2" X 60" = 120 sq inches. Pleats are 1/2" wide
- AC Delco: 1.75 X 52" = 91 sq inches. Pleats are 1/2" wide.
In this category I'd say the Pure One design easily wins.
Anti-drainback valve:
- Wix: Silicone valve contacts smooth base, valve is reinforced with ridges on the top, probably so it won't distort.
- Pure One: Silicone valve contacts raised lip on baseplate.
- AC Delco: Nitrile valve on smooth base.
In this category I'd say it's a tie between Wix and Pure One but the PureOne might have a slight edge for sealing.
Quality of filter core:
- Wix: Metal, some glue voids but on output side and outside of media's inner edges - probably not a big deal as the media edges are well attached.
- Pure One: Metal, no glue voids
- AC Delco: Metal, no glue voids
The Pure One just looks like a higher quality core assembly.
Bypass Valve:
- Wix: Coil spring
- Pure One: Clicker
- AC Delco: Clicker
The AC Delco clicker looked weaker then the Pure One. The Wix coil spring looked the best but since it's longer it takes away from what could be wider filter media. Strictly based on valve design, the Wix looks better.
Overall Outer Can/Baseplate Construction:
The three are all very similar. I'd say it's a tie in this category but some of the Pure One's blue finsh was comming off at the base crimp.
Price:
-Wix: About $4 from Filter1.com
-Pure One: About $4.50 on sale at local retail
-AC Delco: About $4 at AutoZone
Summary:
- I'm going to say the PureOne is the best filter in this comparison largely due to it's media. It also has an excellent anti-drainback valve. Wix looks to be a close second followed by AC Delco.
