AWE ColdFront reservoir for the B8 Audi S4 and S5 3.0T supercharged. CNC-machined from 6061 billet aluminum, it plumbs into the heat-exchanger coolant system to increase supercharger coolant capacity; its flow-through design and added volume lower coolant temperatures, which in turn lowers intake air temperatures. Topped with a laser-etched anodized aluminum cap for easy level checks, it works with the rest of the ColdFront line or the factory heat exchanger.
