Give your MK5 and MK6 GTI/Golf R the cooling it deserves with the Mishimoto Performance Intercooler. Volkswagen might have invented the concept of the hot-hatch, but the spicy Golf can still use a helping hand when it comes to keeping its cool. The stock intercooler system equipped in the GTI is adequate for the daily commute. However, with the popularity of boosting, a component like the tube-and-fin heat exchanger struggles to keep up. Coupled with the combination of plastic in the construction, it's only a matter of time before you start to see boost leaks. We here at Mishimoto started from the ground up with the MK5 and MK6 GTI/Golf R Performance Intercooler. We ditched the plastic in favor of fully cast aluminum end tanks that can handle any amount of boost you can throw at them. We also incorporated an internal air diverter into our end tanks to make use of the full core. The Mishimoto MK5 and MK6 Volkswagen GTI/Golf R Performance Intercooler core replaces the lightweight tube-and-fin construction with a more robust bar-and-plate setup. This heavy-duty construction lends itself to improved durability and heat dissipation. Our core has a 46% increase in core volume with a 97% increase in external fin surface area. Combined with our improved end tanks, the complete package improves flow by 9% and drops 20 F from the charged air across the core. The Mishimoto MK5 and MK6 GTI Intercooler Kit also includes 5-layer silicone couplers and a CNC-machined adapter to ensure a perfect fit with the stock pipes. This intercooler is also backed by the Mishimoto Lifetime Warranty for a worry-free installation on your Volkswagen.
