CTS Turbo S55 F80/F82/F83/F87 BMW M3/M4/M2 Air-to-Water Intercooler Upgrade

CTS Turbo's air-to-water intercooler upgrade replaces the factory heat exchanger on S55-powered BMW M vehicles with a significantly larger core. Designed for F80 M3, F82/F83 M4 and F87 M2 applications running increased performance, this system delivers superior heat rejection to maintain consistent intake charge temperatures under sustained load. The larger core surface area and optimised internal flow paths reduce heat soak during aggressive driving or track work, supporting reliable power delivery when tuning beyond standard outputs. Direct bolt-in fitment ensures straightforward installation without cutting or permanent modifications to the vehicle.
