The Billet Pro Series check valve is a larger, higher flowing check valve than our standard check valve. It generally will increase the vacuum through the catch can and equate to better PCV evacuation. Better evacuation can translate to better MPG and low speed drivability. It also uses a precision-weighted ball to ensure quick response time and a proper seal.
Replacement O rings are available if you need to replace them when servicing your UPR catch can. The O rings are custom made for the catch cans and will not be easy to find at a hardware store.
Billet One-Way Crankcase Breather Kit. This is a direct replacement for the factory oil fill cap that vents unwanted crankcase pressure to the atmosphere and improving overall performance. Incorporating a High-Performance check ball keeping unmetered air from entering the crankcase. The main benefit is that it drives just like stock until you get into BOOST and it releases unwanted crankcase pressure beneath the pistons during the down stroke. Basically, it frees up Horse Power that your engine never had the ability to utilize until installing this UPR Billet One-Way Crankcase Breather.
