The UPR Clean Side Separator allows fresh, filtered air from the air inlet tube to enter the crankcase as the factory intended but will separate oil vapor and keep it from exiting the clean side when the crankcase pressure is high. Once regular driving resumes, the engine air will pull the oil mist back in.
The Billet Pro Series check valve is larger and higher-flowing 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.
The one-way crankcase breather is a breather with a one-way valve. It allows excess crankcase pressure to exit through the breather when under boost. It will close when crankcase pressure is normal and keep unmetered air from entering. Installation can’t be easier! Remove your oil fill cap and install the UPR Billet One-Way Breather. Highly recommended on Boosted engines.
The drain line kit is our most popular drain option. It includes a drain valve, hose, and fittings needed to install the drain valve. It allows the user to relocate the drain somewhere more accessible, like the wheel well opening or bumper area. ( You would choose either the Magnetic Drain Plug or the Drain line kit – not both. If no drain option is selected, a standard plug will be installed)
