This universal Air Pump Simulator wires directly into your BMW's engine harness to eliminate the need for the factory air injection pump system. This is designed for off-road use cars, dedicated for the track and racing, that do not need the secondary air injection system (SAI), so that both the pump and air valve can be eliminated. This simulator is needed to prevent a check engine light and emissions related fault codes stored in the ECU.

Removal of this air pump and air injection ports is common with performance headers and race-prepared cars. This part is sold for off-road use only, and is not intended for road going cars. 

This version is made for custom wiring, and is not "plug and play." This is useful on a race car where you want to eliminate as much wiring as possible, and have this module nearest the ECU, and want a clean/custom installation. This is also a much more affordable option, as the connectors don't have to match the factory wiring. (If you are looking for Plug and Play, we have a kit specifically for that as well. See BimmerWorld number APS_PNP instead.)
