The mantra behind the grandfather of all hot-hatchbacks has long since been that big things come in small packages. The 2015 - 2021 Golf TSI/GTI/R's and its intercooling system are about to receive a much-needed overhaul with the Mishimoto Performance Intercooler Kit. The stock system can be best described as the meat in an intercooler sandwich. It's no wonder with it placed directly between the radiator and AC condenser that this tube-and-fin constructed intercooler has trouble keeping up. Where this lighter core coupled with plastic end tanks might be suited for mass production and tame street driving, it will struggle to keep your intake air temperatures down under more intense driving, especially after the boost is turned up. The Mishimoto 2015 - 2021 Volkswagen MK7 Golf TSI/GTI/R Performance Intercooler, armed with an arsenal of cooling technology, takes the place of the stock intercooler. Our engineers were able to squeeze in a larger core, increasing the overall volume by 89-percent over stock and bumping up the external fin surface area by 162-percent. On top of the larger core, our all-aluminum, TIG-welded intercooler features a more robust bar-and-plate construction for better heat dissipation characteristics. In addition, the cast aluminum end tanks are integrated with airflow diverters to ensure use of the full core. In addition to the more robust intercooler, our Performance Intercooler Kit for your 2015 - 2021 Golf or Audi A3/S3 includes our Performance Intercooler Pipe Kit. We ditched the stock plastic piping and rubber couplers for mandrel-bent aluminum piping and 5-layer silicone couplers. Our piping increases the air channels to and from the intercooler to 2.75 inches, resulting in a 30-percent increase in flow.When combined, our innovations for the MK7 intercooling system yielded max power gains of 14.5 whp and 13 wtq on the stock tuning. In addition, our charged air cooler dropped intercooler outlet temperatures by 23 F
