APR has designed a cooler running thermostat system to aid in performance and durability. By keeping the engine temperature 20 degrees cooler, we are able to run closer to MBT (maximum brake torque) without inducing detonation while reducing catalyst temperatures. In addition the inducted air heat transfer is minimized resulting in a greater mass air flow.
