Description
 

The stock intake plenum on your E46 M3 is great for what it does for a stock car - it is very capable of moving the air required to make the stock 333 Hp and with the minimal amount engine intake noise a luxury car should have. But if you are upgrading your car with an exhaust and headers to move more air to make big power, this carbon airbox has the proper design to support the effort.

These airboxes are reproductions of the BMW Motorsport and CSL parts with a few changes to make them work even better. Made from high grade carbon and very high quality construction, with internal trumpets, proper fittings, unlike many cheap copies from Europe that only look the same on the outside from 10'.

Available in two versions to fit 2001-2006 M3. 2002+ MZ3, MZ4, and transplant cars with S54 engines may require some modification for fitment:

Street/Race (Alpha-N Tune) - 120mm intake, internal BMW Motorsport panel filter (included), fitting for air temp sensor (not included), no mass air fitting. Requires alpha-N type ECU programming or standalone engine management (inquire with us for options). This plenum is great when packaging is an issue due to the internal filter. For an internally stock engine, this version plenum makes the most power.

Motorsport - 200mm intake, internal BMW Motorsport panel filter (included), fitting for air temp sensor (not included), no mass air fitting. Requires alpha-N type ECU programming or standalone engine management (inquire with us for options). Recommended for use ONLY on built race engines making 400+ Hp.

An alternate air temp sensor (PN 13 62 1 725 323) is required when converting to Alpha-N and is available separately. Installation requires splicing a plug for this part to your existing HFM wiring.

We can special order this part to be used with the stock HFM, but we do not feel this part can be tuned properly without Alpha-N and we do not support an HFN-based box with software.
