Mishimoto 2015+ VW Golf R and Audi S3 Performance Auxiliary Heat Exchanger Part MM-RAD-MK7-15A

The VW/Audi MQB platform is the perfect candidate for a sleeper street build or full-blown track monster. Whether it's a VW Mk7/MK8 Golf R, Audi 8V S3, or 8S TT 2.0TSi, the potential power of the TSI/TFSI engines is incredible. Simple bolt-ons and a tune can net you over 100 horsepower and 120 lb-ft of torque, but with great power often comes great heat.All that power requires powerful cooling, especially considering the MQB platform vehicles use coolant to cool the engine, transmission fluid, and oil. Even with up to two auxiliary heat exchangers, these vehicles can still see reduced transmission performance and oil temps well above the safe limit after a few laps around the track. Luckily, Mishimoto has a solution to keep your MQB VW or Audi cool and keep you on the track longer. The Mishimoto 2015+ VW/Audi MQB Performance Auxiliary Heat Exchanger is the perfect upgrade for your stock auxiliary heat exchanger, DSG cooler, or both! Our auxiliary cooler increases core volume by 52-percent and coolant capacity by a massive 106-percent over stock. The core of the Mishimoto aux cooler also utilizes louvered fins to effectively circulate air throughout the core and boost fin surface area by 68-percent. The dual-pass design balances flow with cooling performance for maximum efficiency, while strutted tubes throughout the core ensure durability through the twists and turns of the road or track. The included stainless-steel stone guard adds even more durability to this 2015+ MQB auxiliary heat exchanger by protecting it against road debris kicked up by the car you're about to overtake. Like all our VW/Audi performance products, this 2015+ VW/Audi MQB Performance Auxiliary Heat Exchanger is backed by our Mishimoto Lifetime Warranty for a lifetime of performance. Aluminum radiator engineered for efficient heat dissipation and optimal engine cooling. Precision-fit design ensures easy installation, corrosion resistance, and reliable performance across varied driving conditions.
