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

Race German has devoted themselves to providing quality products for late model BMWs that cover both street and track applications. Race German has now grown their catalog to a wide variety of models and products geared towards keeping your car looking and running nice. A popular conversion on OBD2 M52/S52 engines, is to convert to the M50 intake manifold. The problem with this is, the OBD2 engine harness uses intake air temperature readings. To solve this problem, Race German has carefully milled down the OEM intake air temperature sensor, and re-threaded to the correct threads that are on the M50 intake manifold. The sensor used is an OEM sensor.

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
