The S58 engine uses a water-to-air charge cooler paired with a heat exchanger (water radiator) positioned at the front of the car. This radiator cools the water flowing through the charge air cooler, and that water in turn dissipates heat from the charge air before it enters the engine. Owners of tuned S58 engines commonly report rapid heat soak in this charge air cooling system, especially during track driving, and high intake temperatures can cause the ECU to reduce power output, or even trigger limp mode.
do88's goal here went beyond just durability. By increasing core volume by 39% and external tube area by 9%, while also integrating a quadruple-pass flow for the coolant (versus the original's dual-pass design), the water passes through the cooler four times instead of two, ensuring genuinely maximised contact with the cooling area. Cooling fins are slightly taller than the original at 5mm versus 4.4mm, ensuring good airflow to the engine radiator despite the increased core thickness, and total fluid capacity increases by 1.4 litres for optimal heat dissipation. Full aluminium construction with durable TIG-welded end tanks, and custom rock guards are included to protect against debris in this exposed front position.
Works with: OEM mounting points and factory components. Fits both automatic and manual transmission cars.
