The main function of the intercooler is to make the air COLDER which results in more compact air w/c means more air molecules coming in the ENGINE making your fuel burn better and faster. BUT! you must make your intake free flowing OR as you may see sa other cars, they put their air intake sa front ng cars sometimes sa headlight to force the air in the intercoolers located behind the bumpers. Mas cheaper option yun Snorkel, around 12t lang compared to intercoolers w/c costs 50 to 70T. Good Luck
