Plug N Play Catch Can One Way Breather (fits 21-25 Ford F-150 5.0, also Fits Whipple Supercharger) UPR – Catch Can One Way Breather Only-Black

UPR’s exclusive One Way Breather catch can! This all new design allows you to have the best of both worlds – a high quality UPR oil catch can, and a one way breather all in one! When your engine is producing boost, cylinder pressure goes up and blow by is inevitable. Higher levels of boost + higher levels of blow by = higher crankcase pressure. UPR’s new design allows the excess crankcase pressure to force the patented internal one way valve open, releasing pressure by venting it to the atmosphere, increasing horsepower while extending seal and gasket life! The catch can features Multiple Chamber and Multiple Stages along with a complex series of Coalescing Filters at different micron levels. Along with being the only Plug N Play Catch Can System featuring a solid mount to the passenger side fender, this system also features a quick release knob that allows you easily remove the catch can for servicing. To release the Plug N Play fittings, just push the button on the fittings to be able to remove the entire catch can without any tools. This is the perfect addition to any supercharged high performance F150!

The high quality filter on the catch can is easily washed with warm water and mild detergent like dish soap. In fact, you could clean the entire catch can with the same mild detergent. If you are planning on building a high boost beast out of your 5.0L F150, this is the catch can kit for you!
2021-up F150 Clean Side Separator (CSS):
Upgrade your existing catch can system with the UPR Clean Side Separator. Includes UPR Plug N Play Fittings to allow you to install the UPR Clean Side Catch Separator without any modifications. A simple plug n play system that will outperform anything available. Manufactured from Domestic T-6 6061 Aluminum bar stock and finished off using only the best Diamond cutters to exceed your expectations of what a superior product should fit and look like. UPR is the largest aftermarket catch can manufacturer in the country. Continually improving our designs to stay ahead of the competition and give you the cutting edge technology of tomorrow today. We are so confident we offer an unconditional warranty on our products to let you know you can always count on UPRproducts.

This Clean Side Catch Separator is especially beneficial to modified trucks or trucks with added Superchargers or Turbo kits. As crankcase pressure builds up under BOOST, it will be forced out of the driver side valve cover fitting. This clean side separator will still allow clean air to enter the crankcase as the factory intended, but will catch oil and impurities when crankcase pressure is high, preventing that gunk from getting into your cold air kit and throttle body. Once normal driving resumes, the Clean Side Separator will allow the oil mist to return to the crankcase.
Installs in 20-25 Minutes.
This UPR Pro Series catch can kit is shipped ready to install even if no upgrades are selected. Upgrades are available to allow you to tailor the kit to fit your needs.

Optional Parts:

UPR Billet One-Way Valve Cover Breather:
These are Valve Cover Breathers with a one-way valve inside of it. These are designed to allow excess/positive crankcase pressure to exit through the breather when in boost. Then it closes to return to vacuum while driving to prevent un-metered air from entering to maintain perfect drivability. These are also ideal for vehicles in very cold or freezing weather as it allows crankcase pressure to escape until condensation or frozen condensation in the PCV hoses melts or thaws. This is a must to ensure maximum engine seal life.

UPR Billet Pro Series Check Valve:
These are larger higher flowing check valves than the standard check valve. It will increase the vacuum through the catch can and deliver better crankcase evacuation. The improved crankcase evacuation translates to increased MPG and more responsive low speed drivability. The arrow printed on the check valve will always need to face away from the catch can. There is no down side to having a check valve in a Naturally Aspirated (NA) application, and a check valve in required in boosted applications. The larger, higher flowing Pro Series Check Valve also has a hex nut on the body so you can disassemble it for inspection and cleaning.

UPR Adjustable Billet PCV Fitting:
The adjustable Billet PCV fitting includes 4 different size jets. It eliminates the failure prone factory PCV and still allows for the needed restriction. Jet sizes and application basics for Adjustable version are explained below.

.100 Jet size is slightly more restrictive than the factory PCV fitting to allow you to restrict the PCV for vehicles ingesting too much oil through the PCV and wanting to reduce oil consumption.

.125 Jet size is slightly less restrictive than the factory PCV fitting to allow you to adjust the pcv to increase flow a bit more than factory for vehicles that only need minor adjustments to eliminate vapor locking in the PCV system.

.150 Jet size is even less restrictive for the boosted vehicles that tow and are driven harder to increase flow more than factory for vehicles that only need more adjustment to eliminate vapor locking in the PCV system.

.175 Jet size is the least restrictive compared to the factory PCV fitting and allows for the largest adjustment of the jets for modified vehicles that generate a lot of blow-by / back pressure to eliminate vapor locking / flooding the clean side of the PCV system with oil.

Replacement O-Rings:
Spare O-rings for the catch can cup. If the O-ring is lost, torn or if it’s just time to replace it due to wear it’s a good idea to have a couple of spares in the glove box. 5050 is the main dirty side catch can and 5043 is the clean side separator.

Drain Line Kit:
The drain line kit includes a drain valve, hose and fittings needed to install the drain valve. It allows the user to relocate the drain somewhere easier to access like the wheel well opening or bumper area. If you select this option you can not also use the Magnetic Drain Plug.
