An intercooler can be a very important part of a forced induction engine. When air is compressed heat is created, the more boost pressure the hotter the air gets. Having an efficient intercooler (or charge cooler) is a must. Generally the standard coolers fitted by the manufacturer will be sufficient enough for a stage 1 remap only. Anything more than this and you will need to think about upgrading your intercooler. We have hand picked some of the best available on the market, we see so many cars fitted with very cheap large intercoolers from eBay because people think bigger is better. This is not the case, time and time again a smaller more efficient will do a better job than the large heavy universal cooler sold very cheaply all over the net!
