CTS Turbo S55 F80/F82/F83/F87 BMW M3/M4/M2 Heat Exchanger Upgrade

Keep your tuned S55 cool and consistent with the CTS Turbo front-mount heat exchanger for the BMW M3, M4, and M2 Competition. The factory unit is small and runs out of cooling capacity once you turn up the boost — this larger, higher-flowing core drops into the stock location and keeps intake air temperatures in check.

Why it works

• High-efficiency double-pass aluminum core, larger and higher-flowing than factory
• CNC-machined mounting points and hose connections for a seamless, no-cut install
• Drop-in design — no trimming of factory parts required
• Hand-welded and pressure tested
• Integrated vent makes bleeding air from the cooling system easy after install
• Does not restrict airflow to the radiator or AC condenser
