Ive been running motorcracft FL-IA's from ford 5.0s. starting to wonder if its the cause of my low oil pressure
1 Wix
2 NAPA Gold 51515
3 Mobil 1 M1-301
Those numbers for a Renix or HO? Just pointing out the Renix has Metric threads and the newer HOs switch to SAE threads.
Go the dealer, buy this:
OIL FILTER METRIC TO SAE:
53007563AB
About $8, don't forget to remove the metric filter decal.
The Wix number may be 51515, but last time I checked the Napa gold number 1515 (this is the Ford FL-1A filter used on ford 4.0L and 5.0L engines) http://www.napaonline.com/NOLPPSE/(S(5nyjd5zwswsw1e55mgjk3sfe))/Detail.aspx?R=FIL1515_02179397071 Wix

So what's this part - a replacement filter nipple? IIRC, the gasket dimensions are the same, so it's just the threads on the nipple that are different, right (M20-1.5 vice 7/8"-14 or so?)

Just like the Napa is a rebadged Wix, isn't the K&N a rebadged Mobil with a hex tacked on the end?
I guess I just don't understand the obsession. Can thickness? We're not running 20w-50 in a big block Chevy racing engine @ 8000 revs. Capacity? Really just means that if your drainback valve lets the filter empty there's just that much more 'dry' time at startup. Plus we never even approach dirt-holding capacity at our change intervals. Synthetic vs glass vs paper media?
As long as a filter is good down to about 20 microns filtration, has decent flow, and a good anti-drainback valve, there just isn't any point spending a bunch of money. Even the cheapo Wally World Super Tech filters (made by Champion labs) meet this criteria. There is an immediate point of diminishing returns after that point and spending a bunch of money for a perceived benefit to humor our anal-retentive side is just throwing $$ away.
Yeah, there are bad filters too (Fram Tough Guard). But it's about design and measurable performance parameters, not price.
Go read about the cans that busted and took out an engine when the can failed due to over pressure, or poor seams let go and leaked under pressure, or week cans, or a failed pressure relief valve blew up the can, before you go throwing stones out their. I would never use paper for an oil filter, and 90% of the filters out their, especially all the cheapos use paper.
If you want to risk replacing the most expensive part of the Jeep to save $5 go ahead. "pay me now or pay me later" as the saying goes.
Dirt holding capacity? Depends on the prior user, and how much crap he let build up in the engine. I use the bigger filter for insurance, and since it is 2 times bigger, I can use it 2 times longer, thus cutting the per change cost in half. So who is being "anal-retentive" now?

Touche! Guess the bigger filters might make sense in that regard. I still think they could be trouble if they allow drain-back after sitting for a day or two and need to 're-fill' when the engine is started.
As far as can failures, seems that would have to be a seriously defective can or something wasn't functioning properly in the engine to build pressure that high. I have heard of it happening though.
I guess what I'm saying is that for me, $7 for a NAPA Gold filter is reasonable because it has the right construction features, performance specs, and quality to alleviate 'bad filter' concerns altogether, but that for me anything above and beyond that is overkill. Just my opinion, of course.
'Pay me now or pay me later'? Wasn't that Fram's slogan before they were purchased by Allied-Signal and turned to shite? Now that's some irony!
