The Sniper EFI remote IAC (Idle Air Control) and plug is designed to gain installation clearance on some Sniper EFI 2x4 installations. With select intake manifolds, the distributor housing and IAC valve on the back of the Sniper EFI throttle body are fighting for the same real estate. This plug and play remote IAC kit utilizes the factory Sniper EFI wiring and IAC connector to relocate the IAC off of the throttle body for a clean installation. The included IAC bracket ensures the IAC valve is securely mounted to the throttle body. The Sniper EFI Remote IAC comes with a filter preinstalled. The IAC Plug is included, with this kit to plug off the IAC port on the main body. The IAC motor is not included in this kit, you will need to re-use the IAC supplied with your Sniper EFI throttle body. The IAC service part number is 543-105, if a new one is needed.
