Product Description
VTT BMW Billet One-Way Crankcase Breather
VTT is happy to introduce the first and only available plug-and-play crankcase breather kits for ALL BMW applications that use the two-prong oil tab style oil fill caps. 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.
Can be used by itself with the stock PCV system to eliminate crankcase pressure or with any number of PCV setups for the ultimate in crankcase pressure relief
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 MOST, NOT ALL BMWs with the two-prong style oil fill cap including but not limited to N54, N55, S55, S54, S85, S63, S63TU, and N63. There are factors that may stop it from fitting your platform such as valve cover style etc.
ONLY CHOOSE BILLET VALVE COVER IF YOU ARE RUNNING A VTT BILLET OR CAST ALUMINUM VALVE COVER. ALL OTHERS CHOOSE STOCK VALVE COVER
This is a SERVICE item, it is designed to capture and hold oil that is pulled from the spent gasses when it gets saturated, it must be cleaned
Breather sits about 2-1/8" tall from the valve cover oil cap area, and the filter is 2-3/4" in diameter
