A Mishimoto Uprated Top-Mount Intercooler is a great way to improve the performance of your Subaru. An uprated intercooler increases power by reducing inlet temperatures. Cooler air contains more oxygen, so the engine can make more power. Improved performanceLess power lossHigh quality aluminium constructionAn intercooler serves a vital function on turbocharged applications. Forced induction creates heat as you compress the air into the engine. It's important to then cool it down again. Hot air contains less oxygen and increasing inlet temperatures can increase the chance of detonation.Almost all vehicles with turbocharged engines come with an intercooler of some sort. Hot air from the turbo is passed through a core which then has air flow over it. This cools the air down before it is fed back into the engine.Mishimoto use a bigger, more efficient core which can flow more air more quickly. This alone can result in more power. It also prevents loss of power as temperatures rise. Mishimo
