Heat is the enemy of any engine, especially those with performance upgrades. However, this is commonly overlooked when tuning Golf MK7 R engines. Factory auxiliary radiators were not designed to handle the dramatic increases in engine temperatures following engine tunes and performance upgrades. If you have already or are planning on tuning your engine, then our Golf MK7 R Performance Auxiliary Radiators are a necessary upgrade from your stock auxiliary radiators. Thanks to our dual-pass circuit design, 50% core volume increase and 30% heat dissipation increase, it will be much easier to manage those temperatures effectively. Besides, they just look better than those cheap plastic Golf MK7 R factory auxiliary rads.
