18 inch Intake Air Temperature (IAT) Extension Harness for 2005 - 2010 NON-VVT HEMI equipped vehicles. This harness allows the IAT sensor to be relocated for proper fitment or lowered IAT's.
Lower IATs may be achieved by relocating the IAT sensor away from the throttle body, and engine heat. Wanna read up on it? check out this thread on LXForums.com
