A big part of the EcoBoost engine that we like to keep under control is the oil. More specifically, using a catch can that truly catches and works the way it was intended like the UPR Products 2015-2021 Ford Mustang EcoBoost 2.3L Turbo UPR DVCC Dual Valve Catch Can. This is the only catch can that is proven to work best for the majority of EcoBoost Mustang owners.

Now even though the UPR DVCC has been proven effective, there comes a point when pushing your EcoBoost that you may overpower the system and need crankcase pressure vented. For this the UPR team has created the UPR Products 2.3 Mustang EcoBoost One Way Breather Tank.

UPR One Way Breather Tank is the perfect solution to vent and catch any excess oil being stirred up due to excess crankcase pressure.. The UPR One Way Breather Tank attaches to your oil fill cap, so you don't have to worry about interfering with your UPR DVCC setup. It attaches to the oil fill cap using a CNC billet adapter assuring a perfect fit and seal, leaving no room for leaks.

The UPR One Way Breather Tank will come with the canister, with the vent to atmosphere (VTA) filter on top. It comes with the option of either chrome or black finish. The bracket apparatus comes with a safety line (NMRA Approved) The Can will be installed on the driver-side strut tower where there is a single-hole bracket, like the one you find on the passenger side.

The kit comes with its own hardware including an allen key for installation. 

Customers who will benefit from the UPR One Way Breather Tank are those who are big turbo and need to vent crankcase pressure. So if you're pushing close to 500whp or more you'll definitely be needing this catch can.

Or like in Bobby's case, you can just get it because it looks good!
