Why choose this cooling upgrade

The S58 uses a water-to-air chargecooler system that responds brilliantly to a larger, more efficient front radiator. By increasing core size and fin density, this Mishimoto unit stabilises intake temperatures during repeated pulls, hot weather and extended sessions. It is a proven bolt on solution for stock cars and Stage 1 or Stage 2 remapped builds that demand reliable, repeatable performance.

Built for real world performance and durability

No plastic end tanks. No compromise. The fully aluminium, TIG welded design with CNC ports and strutted tubes provides strength and long term reliability, while the dual pass layout and louvered fin pack deliver a tangible cooling advantage over the OE cooler. Included rock guards add essential protection on the road and at the circuit.
