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.
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 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 clamp all work together to keep crankcase pressure where it belongs, out of your crankcase.
This breather will fit:
ALL BMW's with the two-prong style oil fill cap including but not limited to N54, N55, S55, S54
NOTE: NOT ALL THE MODELS LISTED HAVE THE SAME HOOD CLEARANCE, WE CANNOT SAY WHICH MODELS WILL HAVE CLEARANCE ISSUES, AND WHICH WILL NOT AS WE HAVE NOT TEST IT ON ALL MODELS. IF YOU ARE ORDERING THE BREATHER FOR ANYTHING OTHER THAN AN N54 TEST 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 OF REPORTED CLEARANCE ISSUES: N55 E/F 3 SERIES
This oil filter housing cap is constructed from high-quality billet aluminum, complete with a black anodized finish for added corrosion resistance. Designed specifically for the S54, this lid replaces the OE part and accepts the OE o-ring.
This part features two 1/8-27 NPT holes that can be used to incorporate oil temperature and oil pressure sensors. Port plugs are included to block off the ports if they are not being used.
Machined with care in-house at VAC Motorsports for perfect fitment, these lids are a perfect replacement for enthusiasts looking to seamlessly integrate oil temperature and pressure sensors without tapping into their oil pan.
