UPR vs JLT vs FPP

Hey all, sorry if this is redundant, but haven’t been able to find many opinions on the UPR’s.
H3628 is finally gonna get a set of air/oil separators. I was wondering what the pros and cons are of the choices above. I’m leaning towards the UPR separators. But the others are still on the table. Fire away!

You will only need the right side UPR, unless you are constantly tracking or racing the car. For normal driving and occasional track days the right side only is fine, the left side will not collect any oil.
I went with the FP version to keep the factory look and simplify the installation. The unit works great but the main issue you will read about with the Ford Performance unit is about removing the oil that is collected.
It is not a big deal, just remove 4 easy screws, pop the cover and use a large syringe to empty the chamber. It takes all of about 2 minutes. I use my vacuum brake bleeder to remove the oil, then I can measure the amount on the spot.

I also went with the Ford Performance version. I secures the reservoir to the valve cover so it won’t shake around like JLT version. And a side note, Ford can’t complain of aftermarket parts. It services in minutes, passenger only is necessary.

Thanks for the info, does anybody have the UPR’s? I like the stock look of the Ford Performance but the hoses on the UPR’s seem to be more robust and finished for not much more money.

Hey Jakester, I have the JLT and it works great and doesn't really move around. Also much easier to unscrew the canister to empty. The newer version holds 3.0oz and I pull about 1oz out every 1500 miles or so. The FP unit is nice too! Like was stated above, you only really need it on the passenger side, (unless extreme use is anticipated). FWIW, the JLT unit unclips in about 5 secs., so extremely easy to remove and service. Funny you ask about the UPR unit as I'm looking into that one for my new Raptor and trying to learn why they have 3 hoses - with one going into the intake tube (that you are required to drill). Not sure about the GT350 (UPR application) though haven't checked it out for our cars. All do the job, I'm liking the simplicity and ease of use with my JLT...JMO!
I got the FPP both sides. I like the factory look. So far I haven't had to drain them. They look good and the hoses are just like the stock hoses.

The FPP is CA EPA authorized so you won't fail a visual inspection. I don't live in CA so I don't need to worry but it could be a factor in your choice.

I have the UPR’s both passenger and driver; recently installed. I don’t have experience with the other units passed what’s already been said. What I can tell you is that the quality and construction of the UPR’s is fantastic. Totally bomb proof and I’m 100% happy. I read the UPR’s collect more oil that the JLT but have no clue personally. I’m sure they all work fine.

I have installed the FPP version on both sides and use the brake vacuum to remove the oil as well. The FPP drivers side does make access to the oil dip stick a bit of a challenge.
After 3600 miles I have removed 2oz from the passenger side only. All miles from normal driving NO track time.
All catch cans work the same and work jsut as good as the next one on principle alone. This is literally an item where you just pick the one you like the looks of best. Dead serious. I went with Ford like many others; that clean factory install look. Can’t beat it. All will do the same job.
I went with Ford Performance too. Factory parts and mounting both sides. Happy with them. Servicing is easy, I use a couple of Scott shop towels to soak up the oily mess inside. Driver side is dry but I haven't been to the track yet with my 2018.
My advice: know yourself.

I knew that if I picked one that was fiddly to empty, I wouldn't do it often enough, so I bought the JLT (dead simple, just unscrew the can, dump it, and screw it back on).
Agree. I like fiddling with my car. I emptied mine at a little over 1000 miles and there was very little. I'll check it again at 3000. I think any of these systems do the job of keeping the nasty stuff out of your intake.
