Subject says it all. Which is better. Ive used both, but have been using the pure 1.
Thanks

I share you concern about the location of the bypass but I have found no data to suggest it is a "real" problem.quote:

Wix and NAPA Gold have the bypass valve in the threaded end (so does Motorcraft, which is made by Purolator). That to me, makes them a cut above the otherwise excellent Purolators with their bottom of the can bypass, where the oil has to pass alongside the dirty filter element to get to the bypass (possible contamination concerns though never heard of it being a problem). As for Purolator, I like Premium Plus as I think Pure One may be somewhat more restrictive.
True. I use the Purolator L40017 (Motorcraft FL299), which has the threaded end bypass. Actually I really like the Fleetguard LF697 but it has the bypass in the bottom. Flow is astounding though at nearly 16 gpm.quote:

That is the beautiful thing about GM filter apps. The bypass is in the block, so it is ALWAYS at the threaded end!quote:
Both are good filters with a silicone ADBV. The Pure 1 definately filters better and seems to have more capacity, the Wix flows a little better.
I'd buy the Pure 1 because of the construction and filtering ability.
Your right, the WIX #51372 for Ford modulars has the bypass in the rear.quote:

I would think for liability reasons.quote:
What gives? I say I use a whatever wix filter, and ask if they have an oversized filter with the same specifications as the number I gave them, and they say we dont do that. Why??????????????????????????????
Unless it's a Saturn.quote:

I run Purolators in my GMs, and Motorcraft FL1-A on my Ford.
For sure! And look up the filter manufacturer's warranty. It only applies if you use the exact filter number their catalog says to use. Anything else and you are on your own. So what, says Iquote:

It's even worse for VAG 1.8T owners, because we are now required to use oversize filters to expand our meager mis-engineered oil capacities from 3.7 to 4.5 qts., but most filter manufacturers and parts houses show only the original smaller filter, such as a Bosch 3421. (VAG increases the confusion by making the two part numbers, 06A-115-561-B (small) and 068-115-561B (large), sound almost the same.)quote:

Sorry, I totally missed this post before. The Wix Racing has astounding flow. I thought the Fleetguard was remarkable and is compared to some brands. I called Purolator and they gave me gpm for their versions of the FL400s (L20195), FL1A (L30001), and FL299 (L40017) as 3 gpm, 4 gpm, and 7 gpm. Wix told me both the 51773 (FL299) and 51515 (FL1A) are 7 - 9 gpm. Now I wonder what Motorcraft filters flow. Bet those Wix Racing filters cost a lot.quote:

Paul,
speaking of flow have you seen the WIX Racing filter specs?
