E46 M3 Carbon Motorsport/CSL Airbox

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:

  • CSL/Street - Retains fitting for stock mass air meter. Uses external cone filter, not included.
  • Motorsport - Internal BMW Motorsport panel filter (included), 200mm intake, no mass air fitting. Requires alpha-N type ECU programming or standalone engine management (inquire with us for options).
  • BimmerWorld Spec - Includes taper and mass air fitment, uses external cone filter, but retains ability to install internal Motorsport panel filter if needed.
