Our E46 M3 Carbon Plenum / Airbox - Motorsport 2000MM Kit is the ultimate upgrade for your stock intake plenum. The stock M3 setup is fine for a stock car, and it's perfectly capable of moving the air required to make the base 333 Hp with the minimal induction noise - as a luxury car should have. On the other hand, if you're upgrading your car with a built race engine, exhaust and headers to move the most air possible and make big power, this carbon airbox has the ideal design to support the effort.
This carbon airbox is a reproduction of the BMW Motorsport part with a few changes to make it work even better. This high-quality unit is made from high-grade carbon fiber with internal trumpets and proper fittings, unlike many cheap copies from Europe that only look similar from the outside, and only from 10' away.
200MM Motorsport Version- 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 maengagement (inquire with us for options). Recommended for use ONLY on built race engines making 400+ Hp.
Note: For engines with stock internals, the 120MM version is available in a separate listing.
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.
While we are able to special order this part to be used with the stock HFM, we do not recommend this. We don't feel this part can be tuned properly without Alpha-N or standalone tuning, and we do not support an HFM-based box with software.
E46 M3 Fitment Note: 2005-2006 E46 M3 will require intake plenum boot, part #11617830265. See below for link.
Non-E46 Fitment Note: 2002+ MZ3, MZ4, and S54-transplant cars may require modification for fitment.
