An intercooler is a vital part of the intake system on a turbocharged or supercharged car. It cools the air going into the engine down. The cooler the air, the more oxygen it contains, and the more power the engine can potentially make. An uprated Revo Intercooler can significantly boost the power your engine makes.26.9% Increase in the frontal surface area improves heat transfer and achieves better cooling and more powerA 53.9% increase in external core volume allows greater airflow to cool faster, giving you access to more power throughout the rev rangeLowers intake air temperatures by up to 33°C (vs. the stock intercooler) and allows you to drive harder, for longerDuring Revo's dyno testing, approx 14.7HP and 25Nm Torque gain at the axle were achievedA supercharger or turbocharger increases power by compressing air to force more of it into your engine. More air means more power. Unfortunately compressing the air heats it up. Hot air contains less dense oxygen which can limit power.
