Gen II - Our Gen II kits emulate the operation of the SAIS and ECM will read as Ready/Completed. It also eliminates all trouble codes dealing with the SAIS with the exception of the pressure sensor. Installs at the Air Injection Driver and Air Switching Valves. This is our recommended solution because it is the most comprehensive kit we offer.

Gen I - Our Gen I kits will prevent the SAIS from operating on a cold start and ECM will read as Not Ready/Incomplete. With this unit, all of the SAIS parts/components will need to remain in place for the computer to see continuity to them. Installs at Mass Air Flow sensor and Engine Coolant Temperature sensor. Also, the starter relay wire will need to be run from the bypass module to a terminal inside the fuse box.
