CTS Turbo Upgraded Heat Exchanger for BMW S58 G80/G82/G87 M2/M3/M3C/M4/M4C

Turn up the boost on your G8X with confidence. The CTS Turbo charge air cooler upgrade for the 2021+ BMW G80 M3, G82 M4, and G87 M2 (S58 engine) keeps intake air temperatures as low as possible so you get cleaner ignition, less timing pull, and more power — whether you're on the street or the track.

Why it works

• Dual-pass high-efficiency core greatly reduces charge air temperatures
• Direct fitment for G8X M2/M3/M4 — no modifications needed
• Robust aluminum core with optimized fin pitch for maximum heat dissipation
• Lightweight despite its robust construction
• Plug-and-play install with all necessary hardware included
• Upper and lower rock guards protect against road debris

Specifications

• Construction: 100% TIG welded aluminum, pressure tested to 50psi
• Core: 2-row, 633mm x 458mm x 40mm high-performance core

Fitment (RWD, xDrive, 6-speed manual and ZF8 automatic)
