BMW E46 Crankcase Pressure Regulator Valve | S54 3.2L Engine is a crucial component that ensures proper crankcase ventilation by regulating oil vapor flow into the intake manifold, preventing excessive oil consumption and buildup. Designed specifically for BMW E46 models with the S54 3.2L engine, this valve helps maintain engine efficiency and performance. BMW engines are known to experience oil separator freezing in cold weather if not fully warmed up, which can lead to howling noises and oil leaks. To ensure a thorough repair, replacing the valve cover gasket when changing the separator is highly recommended.

Helps maintain proper engine ventilation for peak performance
Reduces the risk of oil separator freezing and associated leaks
Direct-fit replacement for BMW E46 models with S54 3.2L engine
High-quality materials ensure durability and long-lasting performance
Recommended to replace the valve cover gasket for a complete repair

Protect your BMW's engine from excessive oil consumption and leaks by replacing a failing crankcase pressure regulator valve with this premium-quality replacement.

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem.

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking.

The CSL Airbox is one of the most demanded improvements among BMW M3 E46 enthusiasts. That is both for performance gain and for the sound it brings to the car. On the other hand, it is a laborious, time-consuming, and expensive modification. For those who are looking for a similar sound to the CSL airbox but are not looking for HP gain, we have developed the Karbonius OEM Style S54 airbox. It is a simplified version of the CSL airbox, that, apart from a louder sound from the engine (+12 dB compared to plastic OEM), gives an awesome appearance and allows for easy installation using the stock elbow and MAF sensor. No need to remap! Regarding power increase, we got +4HP in a recent dyno test compared with the OEM airbox. Not really significant considering that dynos can have a 2% margin error. In conclusion, and pending new tests in the future, we can say no significant power increase and no HP loss. NOTES: Need to install with CSL Crankcase breather hose -- BMW # 11157833649) In SMG version, need to install a Genuine BMW CSL SMG Expansion Tank -- BMW # 21532282549 Fitment: BMW M3 E46 BMW Z4 M
