Does anybody know the best way to clean in intercooler? When I open the hod of my WRX to look at the engine or to show somebody it is kid of an I sore to see that layer of dirt picked up by the intercooler from the hood scoop. Since I am sure that there are those of you who put your cars up for show, what is the best way to clean the surface of the intercooler? And while I am asking, what is your most recommened method to detailing the engine. Any comments would be greatly appreciated!!!
