ECS Tuning aluminum intercooler upgrade kit engineered to replace the factory intercooler core on turbocharged Audi/Volkswagen MQB and EA888-based platforms. The kit uses a cast-aluminum end tank and bar-and-plate aluminum core (roughly 40% more efficient than the factory unit) to lower intake air temperatures, reduce pressure drop, and support increased boost levels, and is pressure tested to a minimum of 3.5 bar with zero leak-down. Fitment: Audi A3/S3/TT and Volkswagen Golf/GTI/Golf R (MQB platform, 1.8T/2.0T EA888).
