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. Incorporating 4 internal baffles to control oil. Ideal for all street and race applications to handle engine blow-by and any boost levels.
