If you have a later model Turbo I car that came from the factory with the "blow through" style intake manifold (such as a 1988 2.2 Turbo I car) or a 1989-1992 2.5 Turbo I car, and you are wanting to add an intercooler, you will need to add the wiring for a charge air intake temp sensor.  These harnesses developing at the Chrysler/Shelby development center will allow you to run an intercooler on your car and they were designed to be plug and play which makes the process of intercooling your car much simpler.   Price is for 1 harness and thus does 1 vehicle.  We have approx 4 in stock.
