S55 Charge-Cooler Heat Exchanger

Front HX · low-temp circuit

The other half of the S55's water-to-air system: the front-mounted heat exchanger that rejects the charge heat to ambient. A larger, denser core here is what keeps the low-temperature circuit — and therefore the manifold charge cooler — from heat-soaking in sessions. Pair with the top-mount cooler and a healthy pump.
