do88 VW Golf GTI MK7 (MQB) Auxiliary DSG Radiator

The DSG transmission in the Mk7 Golf GTI relies on its own dedicated auxiliary radiator to manage fluid temperatures, separate from the main engine cooling system. Under sustained hard driving, particularly on track or during repeated aggressive acceleration, the factory auxiliary radiator can start to struggle, letting transmission fluid temperatures climb higher than ideal and risking both shift quality and long-term transmission health.

do88's replacement is engineered specifically to address this limitation, delivering genuinely improved cooling capacity over the factory unit so the DSG can maintain more consistent fluid temperatures under demanding conditions. This is a worthwhile upgrade for anyone tracking their GTI, autocrossing, or simply pushing the car hard on a regular basis, where the factory system's limits become most apparent.

Works with: OEM mounting points and connections. Genuine drop-in fitment.
