I don't think the "latest design" of the Titanium is wire-backed. The latest design is the new non-wire backed media. What you want is the original design Titanium.
The Endurance does seem like a good option, BUT it also seems to be the exact same filter as the Royal Purple - yet the test results for these supposedly identical filters were very different:^^^ Yep you are looking for old stock. Or give up and get Endurance from Wally's.
Sadly just about everything I've seen that uses the 3506,3675,or 9837 has a small mounting plate that won't accomodate anything larger than a 3in diameter filter, otherwise I'd run an XG5 on my Trailblazer.Could you use the XG5 (PH5) Ultra? I have a fair amount of wire backed OG Ultra ones, my diesel 6.2 Sierra is gone & my brother's Jeep SBC has been laid up for a couple years now.

I'd take their test results with a grain of salt, there's a reason why Ascent charges $500 to do ISO 4548 testing, and you can't just Jerry-rig a good ISO 4548-12 testing rig in your garage, I did some light reading and I don't think they mentioned anything at all about drying the dirt and leaving it in a desiccated container until use which is perhaps one of the most important parts of the testing procedure as the dirt containing any moisture can very easily agglomerate.The Endurance does seem like a good option, BUT it also seems to be the exact same filter as the Royal Purple - yet the test results for these supposedly identical filters were very different:View attachment 189007

Three things: 1) Using only half of the particle count data range to try and rate the overall efficiency of oil filters is a far cry from an actual ISO 1548-12 efficiency test. They should have been getting PC tests for the entire particle range of an ISO 4406 PC test which would give a better data set to rate the results. 2) It's possible that the Endurance has slightly different filter media (Fram specifies the media), and 3) Fram rates the Endurance as 99+% at 20u based on 3 different sized filters, but Royal Purple doesn't claim that same efficiency ... another indication that the media might be different.The Endurance does seem like a good option, BUT it also seems to be the exact same filter as the Royal Purple - yet the test results for these supposedly identical filters were very different:
Way more than that for the full blown test like done in the Ascent testing thread.I'd take their test results with a grain of salt, there's a reason why Ascent charges $500 to do ISO 4548 testing
They tried to mirror the ISO test where a pressure drop above new (like 8 PSI) is used. You don't want the bypass valve to open.I also question BrandRanks testing methodology on capacity loading. They seem to set a pressure drop threshold than actually load up the filters until the bypass valve opens.
There is nothing wrong with those base plate holes. Way more total flow area than the center oil flow hole on the mount spud the filter screws on to. Besides, positive displacement oil pump (the most misunderstood component of an oiling system) will not care one bit if there is a Titanium or Endurance on the engine.Look at how pathetic the Endurance base plate looks in comparison:
So I did it. I drove around and found wire backed Fram Titanium filters for my Corvettes.
Then, like a total sicko, I unboxed them, sealed them up in plastic bags, put them back in boxes and neatly taped the boxes closed.

Also, I bought more filters and cut them open:

The Endurance is really good, but I just love the PowerFlow baseplate of the Titanium so much!

The Endurance louvers are legit open tho:

Endurance weighs more than 50% more!!!!

Yeah was gonna say the 9837 is about 4 inches tall, the FE version is 4.5 inches tall.Can you fit the longer 9837/3675 size? You can find a lot of 6 of the XG9837 filters on eBay for $30 from SAE-Auto, I think some people here have had ok luck buying from them. The 9837/3675 is about 3/4in taller than the 3506, the difference between the 3675 and 9837 would typically be whether the filter has an ADBV or not, but the ADBV is integral to the Ultra's design so the XG9837 has an ADBV even though the TG and Extra Guard variants do not.
I've always purchased the cheapest filter's, knowing it is just a filter and any will be better than nothing and after factoring in a lifespan is about 6 months no other thought has went into the device.. not thinking about it has served me well since I bought my first car in 1976..Allow me to quote myself from another thread ....
Bottom line: filters are changing faster than we can cut them open and track them. As soon as you think you've picked "the best one", it won't be a month from now. While I appreciate Robvette's efforts, they mean little because whatever he discovers now won't be applicable in the near future. It's a crapshoot.
Looks good-but you need some desiccant in those bags to be a true obsessive-compulsive BITOGer! (Disclaimer, I have some in bags with desiccant…)So I did it. I drove around and found wire backed Fram Titanium filters for my Corvettes.

The question is what is the surface area of the individual louvers and what is the quantity vs the standard punched hole center tubes. It may be fine.I don't trust those louvers Zee; how about you?
