BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable. Don't forget to order a valve cover gasket to make your separator change easier.

A damaged, leaking, or missing vacuum check valve can lead to a range of engine performance issues. As a critical component in the vehicle's vacuum system, the check valve ensures proper air flow and pressure regulation within various engine systems. If compromised, it can cause erratic idling, poor acceleration, or rough engine performance. Additionally, a malfunctioning vacuum check valve may trigger the check engine light and could cause your vehicle to fail an emissions test due to improper control of exhaust gases. Timely replacement of a faulty vacuum check valve is essential for maintaining engine efficiency, preventing further damage, and ensuring compliance with emissions regulations.

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
