The HKS Turbo Timer TYPE 0 for your WRX or STi uses a  easy to read Red back light LCD display in a black control unit case. The Type-0 is ultra compact, less then a 1/4 dynamiter in size polyurethane casing, back-lit button controls, a larger color LCD panel, a volt monitor function to monitor battery power, and an auto mode feature that adjusts engine idle time according to the most recent driving pattern.

Make installation a breeze with a turbo timer harness. Simply plug and play.
