Product Information
The AMS Performance heat exchanger is a direct bolt-on replacement for the front heat exchanger in the S58 air-to-water charge cooling circuit, built to fight heat soak during hard driving. A dual-pass core with 35% more core volume and double the factory fluid capacity is capped by CNC-machined billet 6061-T6 aluminum end tanks, with optimized fin height and density and radiused inlet and outlet fittings to cut pressure drop. In AMS testing it ran coolant 16°F cooler than the leading aftermarket competitor and held peak intercooler outlet air to 112.8°F versus 116.4°F stock. No cutting or drilling is required.
