The charge air is cooled via a separate cooling water circuit. Lowering the cooling water temperature is therefore the critical factor in maintaining engine performance, especially during aggressive driving or performance enhancements.\u003cbr\u003e\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe Wagner Tuning upgrade water cooler solves this bottleneck with a 60% increase in volume, which is primarily achieved by increasing the installation depth (from 30 mm to 48 mm).
