UPR Instructions for their Low-Profile Clean Side Separator for Dual-Valve Cans

Posted by Jason Locke on 10/14/2014 to Install guides

Our good friends over at UPR have updated their pretty excellent 2011 to 2014 F150 EcoBoost Dual-Valve Catch Cans with Clean Side Separators with a new clean side separator design that installs directly onto the driver's side PCV port instead of the oil cap neck to give your bay a cleaner look. While this update is a "good thing" at face value, UPR may or may not have instructions for the older CSS design and stuck them with the new catch can kits. Luckily the change was horribly drastic, and there's really only one change in the overall install process. Anyway, here's a link to UPR's updated PDF instructions, and a little explanation below of the differences between the old and new versions of the kit.

2011-2014 F150 EcoBoost UPR Dual-Valve Catch Can Kit

Basically, the older version of the dual valve kit came with a billet clean side separator that installed in place of your truck's oil cap. This is all well and good, but it it did leave this big UFO-looking thing hanging around in your truck's engine bay and wasn't as efficient at capturing PCV blow-by as it could be. UPR's new Low-Profile CSS installs in the driver's side valve cover's PCV port so that it can directly collect blow-by gasses while being able to fit under your truck's valve cover for a much cleaner look. Check out the difference below. The old CSS is on the right, while the Low Profile CSS is on the left.

Anyway, routing the hoses and everything on the passenger's side of the truck is more or less the same, and your post-install should look roughly like the simplified diagram below:

Hey there, I'm wondering if this kit can come with an extra hose and fitting to hook into the passenger side turbo. I understand it would need to be drilled and tapped but that wouldn't be a problem.

Hi i was recently reviewing different catch cans. Would it be possible to get a diagram of what the internals look like on the upr mega catch can. Also does the clean side air seperator require changing or maintenance? Also other models require drilling; is the mega catch can as effective as these models?

I installed the catch can and my mpg went down drastically. It went from 17.1 to 13. What would cause this?

If your service engine soon light came on after install it will drastically affect fuel mileage.

Dear UPR, or Stage 3 I just purchased a 2013 F150 ecoboost with the 3.5L. When I order EcoBoost UPR Mega catch can w/ Clean Side separator in a couple weeks will it come with the new low profile CSS? Thanks, Terry

Hi there I recently got a used mega catch dual valve upr can...I hooked the passenger side up with the one check valve pointing away from the can...and then the drivers side hoses with the T setup from the clean side separator (but the check valve from the separator is pointing towards the catch can?) is this correct with the check valve pointing towards the catch can ?

Just installed the mega catch can with low profile CSS and my MPG went down from 17'ish to 15. No engine lights or codes and the engine seems to run fine. What could be causing this?

I recently ordered and installed a urp catch can with the clean side separator on my 2012 f150 EcoBoost .had some issues running hoses as per instructions due to the afe hot/cold side charge pipes and had to trim the engine cover a little to not Rub on the hoses.my question does the clean side sererator need any maintance and or how does one know if it needs to be changed
