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

The CTS Turbo Air-to-Water Intercooler for BMW S55-powered vehicles—including the F80 M3, F82/F83 M4, and F87 M2 Competition—is a premium, high-performance cooling solution designed to replace the weak, plastic OEM intercooler. Built to withstand higher boost levels and deliver superior thermal efficiency, this intercooler features a high-density dual-pass bar-and-plate core and proprietary cast aluminum end tanks with internal flow-directing fins, ensuring optimal charge air cooling and reduced intake air temperatures (AITs). Lower AITs mean less chance of detonation, reduced timing pull, and more consistent performance—especially critical for tuned or aggressively driven S55 engines.

Designed with precision using in-house 3D scanning, CMM measurements, and CAD optimization, the intercooler is a direct-fit upgrade that requires no modifications. It comes complete with CNC-machined fittings, stainless steel helicoils in the mounting locations, high-quality hardware, and reinforced silicone couplers for a secure, reliable install. Each unit is hand-welded, pressure-tested, and finished in a durable semi-gloss black powder coat, topped with a CTS-logoed cover plate for an OEM+ appearance. Exclusively available through CTS Turbo and its authorized dealers, this intercooler is built for serious enthusiasts who want maximum reliability, power, and cooling performance for their BMW M2 Competition, M3, or M4 equipped with the S55 engine.
