BMW Intake Manifold Components (DISA, Vacuum, CCV, Etc) for BMW E46 M3 S54 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

The intake manifold takes incoming air from the intake and distributes it to each cylinder. Over the years the manifolds have gotten more sophisticated and complex. Most of the additional work that it does is emissions-related - recirculating vapors back into the engine to be re-used. But there are also performance innovations such as BMW's DISA variable intake runners. All of the modern innovations have a part behind it and here you will find replacement components.

In some BMW models there are performance improvements with intake manifolds. These intake manifold upgrades use mostly BMW parts and are a direct replacement for your stock manifold. We offer manifolds and kits to make the conversion work easier.

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.

  • Regulates crankcase pressure to prevent excessive oil consumption
  • 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.

Get the highly coveted CSL experience with your S54! Roaring induction noise, aesthetics and increased performance are just the tip of the iceberg when installing this legendary intake. Its not fair that Europe always gets the cool cars and widgets (excluding E36 LTW, thank you BMW.) The E46 CSL M3 is world renowned as one of the finest cars BMW produced. Covered with parts exclusive to the CSL model, the intake system is one of the most sought after components for non-CSL owners. The CSL intake plenum is your chance to experience the life altering CSL intake. For starters, after installation you are left with a completely transformed engine bay. You can try your very best to resist from sticking your arm in the massive inlet of the plenum but we doubt that you will be able to hold back. Turner's CSL intake plenum boasts a full carbon fiber construction with velocity stacks engineered to outflow the factory air box by over 20% and even outperforms the factory CSL air box on the flow bench because of the improved design. The CSL intake does not feature any sound dampening or silencer and allows your S54 to let out its full roar that can be heard clear through the cabin for an experience that makes you smile ear to ear. Paired with the Active Autowerke Alpha N Tune we have seen gains of up to 43 hp and 26 Ftlbs of torque in a healthy naturally aspirated S54. Performance Benefits: Airflow increased by over 20% Increased throttle response Tuning benefits far beyond the factory intake Weight reduction Roaring induction noise for both driver and spectator

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.
