Unleash Consistent Power — Race-Ready Cooling for Your BMW X5 M / X6 M / XM
When you demand more boost, you demand better cooling. The CarBahn Heat Exchanger Kit transforms your BMW’s thermal management — letting you push harder, safer, and more reliably.
Why You Need This for your X5M/X6M/XM
- Reduce charge air temps = more power — High boost increases intake temperatures. This heat exchanger slashes those temperatures, allowing denser air charge and a stronger, safer burn under load — especially during hot summer conditions (where gains become very noticeable).
- Run more boost with confidence — With this kit in place (and paired with CarBahn tuning), you get the thermal headroom to dial up boost levels without fear of heat soak or detonation.
- Factory-level reliability backed by warranty — CarBahn supports this upgrade with a factory-matching warranty on the engine and drivetrain when used in conjunction with their software.
- Perfect fit for M SUVs & XM — Crafted specifically for the F95 / F96 chassis and tested across the 2020–2026 models of X5 M, X6 M, and XM (including Competition variants).
- Premium quality & compatibility — Designed as a bolt-on performance upgrade in the Air / Cooling system family, with part number CBF9X-2021, this is not a generic solution — it’s engineered for your M-Series beast.
