VTT is happy to introduce the first and only available plug-and-play ONE-WAY crankcase breather kit for BMW S58 applications. With this breather simply remove your oil cap, install the breather, and instantly free up horsepower, improve turbo draining, and remove crankcase pressure, all while adding a cool look to your engine bay. FITS with the engine cover on. The engine cover can be removed, and installed without removing the breather.
Can be used by itself with the stock PCV system to eliminate crankcase pressure, or with any number of upcoming PCV setups, including our VTT Engine catch can for the ultimate in crankcase pressure relieve
Made from 6061-T6 Aircraft aluminum anodized black for a long-lasting finish, 4 stainless steel baffles for complete oil control, a PTFE one-way check ball, a high-quality filter, and a clamp all work together to keep crankcase pressure where it belongs, out of your crankcase.
This breather will fit ALL S58 Vehicles that use the most common oil fill cap design. This does NOT mean it fits all BMW vehicles.
The breather sits about 2.5″ tall from the valve cover oil cap area, and the filter is 2-3/4″ in diameter
NOTE: NOT ALL THE S58 MODELS LISTED HAVE THE SAME HOOD CLEARANCE, WE CANNOT SAY WHICH MODELS WILL HAVE CLEARANCE ISSUES, AND WHICH WILL NOT AS WE HAVE NOT TESTED FIT ON ALL MODELS. IF YOU ARE ORDERING THE BREATHER FOR ANYTHING OTHER THAN MODELS TESTED ON. PLEASE TEST AND CLOSE YOUR HOOD CAREFULLY TO ENSURE CLEARANCE IF IT DOES NOT FIT LET US KNOW, AND WE WILL GET YOU A REFUND ONCE THE BREATHER IS RETURNED.
MODEL LIST WITH VERIFIED FITMENT NO CLEARANCE ISSUES: G8X M3/4, S58 powered X3/4M
PLEASE KEEP IN MIND ON CARS THAT TEND TO HAVE A LOT OF CRANKCASE PRESSURE BEING VENTED EVEN WITH 4 BAFFLES, AND A FILTER YOU MAY HAVE TO REMOVE AND CLEAN THE FILTER AND BREATHE PERIODICALLY TO KEEP IT FROM EXPELLING SMALL AMOUNTS OF OIL MIST IF THE FILTER GETS SATURATED.
