Mishimoto Performance Intercooler Kit for 2015–2021 VW Golf TSI/GTI/R & Audi A3/S3

The MK7 Golf GTI and R may have rally-bred DNA, but their stock intercooling system falls short when boost is cranked and temps rise. That’s where the Mishimoto Performance Intercooler Kit steps in. This complete upgrade replaces the factory tube-and-fin intercooler and restrictive plastic piping with a robust bar-and-plate core and high-flow aluminum piping.

Engineered for the enthusiast who demands more than stock, Mishimoto’s intercooler increases core volume by 89% and improves fin surface area by 162% compared to OEM. This means significantly improved heat dissipation, more consistent intake temps, and better protection against heat soak during spirited driving or track days. The all-aluminum, TIG-welded intercooler includes cast end tanks with built-in air diverters to ensure maximum use of the full core.

This kit also includes mandrel-bent 2.75” aluminum piping and five-layer silicone couplers, replacing the factory plastic charge pipes for increased airflow and long-term durability. On a stock tune, this system delivers gains of up to 14.5 whp and 13 wtq while dropping outlet temps by up to 23°F.

Whether you're street-tuned or fully built, this is a must-have cooling upgrade for any MQB platform build.
