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 dampens engine intake noise. But if you are upgrading your car with cams, headers, etc and are ready 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 three versions to fit 2001-2006 M3, 2002+ MZ3 and MZ4, and transplant cars with S54 engines:
