UPR Crankcase Breather for All Ecoboost Vehicles (Focus RS, Mustang, Fiesta, Focus, F-150)
Recommended for customers with high crankcase pressure (high boost pressure, upgraded turbo, built engine). Should be used in conjunction with a catch can on the PCV (dirty) side of the crankcase system!

- Direct Replacement for Oil Fill Cap
- Releases unwanted crankcase pressure under Boost
- Check Ball prevents unmetered air from entering engine
This fits all Ecoboost Vehicles, select your application above!
*Please note, this vents crankcase pressure which is part of the oil system. This means the air coming out of the crankcase breather can contain oil vapor. Over time this will build up around the edge of the filter. If you have excess crankcase pressure we recommend installing a radium baffle plate and a PCV catch can in conjunction. Again, seeing oil on the edge of the filter is normal operation, you can wash the filter with standard dish soap and water, then blow it out every oil change to prevent excess seeping over time.
