The cooler the intake air, the more oxygen it contains and the better the combustion works. So colder air means more power. However, when compressed by a compressor or turbocharger, the air heats up considerably. To prevent this hot air from entering the engine, you need an intercooler. This cools the air down again and thus ensures more power and less stress on the engine. Due to more boost pressure, standard intercoolers cannot provide the required cooling capacity and the air is too hot. Our upgrade intercoolers from WAGNER TUNING replace the original intercooler plug-and-play. We also offer universally usable charge air coolers and networks from BOOST PRODUCTS and WAGNER TUNING for individual charge air cooler self-construction.
