Breeze by the competition in your 2015-2021 EcoBoost with the installation of a UPR Billet Aluminum One-Way Valve Cover Crankcase Breather Kit. Designed to be a direct-fit replacement for the factory stock oil fill cap, this kit will vent unwanted pressure from the crankcase providing an overall boost to the performance of your Mustang.
Features and Benefits:
- Direct-Fit Replacement for Oil Fill Cap
- Relives Unwanted Engine Pressure
- Increases Horsepower
- Lightweight Billet Aluminum Construction
The effect will be most noticeable once you activate your boost feature. Venting the unwanted under-the-pistons pressure will allow you to use the horsepower that was tied up in the extra pressure resulting in a faster, more powerful engine. This kit is made in the USA of CNC-machined billet aluminum offering a lightweight construction to keep your EcoBoost moving at top speed. Investing in UPR’s Crankcase Kit will benefit any street or strip applications that take advantage of engine blow-by or boost levels and put your S550 ahead of the game.
