VTT is happy to introduce the first and only available plug-and-play ONE-WAY crankcase breather kit for BMW B58TU A90/91 Supra applications. The B58 engine is known for poor PCV and crankcase pressure issues. With this breather simply remove your oil cap, install the breather, and instantly free up horsepower, improve turbo draining, remove crankcase pressure, all while adding a cool look to your engine bay. FITS with the engine cover on. 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 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 1″ PTFE one-way check ball, a high-quality filter, and clamp all work together to keep crankcase pressure where it belongs, out of your crankcase.
This breather will fit ALL A90/91 Supra Vehicles that use the same oil fill cap design. This does NOT mean it fits all BMW vehicles. We have different breathers for different BMW platforms. This is for the Supra ONLY.
The breather sits about 2.5″ tall from the valve cover oil cap area, and the filter is 2-3/4″ in diameter
MODEL LIST WITH VERIFIED FITMENT NO CLEARANCE ISSUES: A90/A91 Supra
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 BREATHER PERIODICALLY TO KEEP IT FROM EXPELLING SMALL AMOUNTS OF OIL MIST IF THE FILTR GETS SATURATED.
