Wagner Tuning Performance Intercooler Kit — F10/F01/F12 535i/740i

At the heart of the kit is a 570mm x 302mm x 100mm stepped bar-and-plate mesh core that delivers 92% more frontal area and 97% more charge air volume than the stock unit. That isn't a marginal gain — it translates directly into lower, more stable intake temperatures under sustained load, reducing heat soak and giving your engine a denser, more oxygen-rich charge with every combustion cycle. The core is finished with an anti-corrosion protective coating engineered for excellent thermal conductivity, ensuring the cooling advantage doesn't degrade over time even in demanding climates or track environments.

Wagner's cast aluminum end tanks are designed using CFD analysis, with internal baffles shaped to guide airflow efficiently through the core and eliminate the pressure drop points inherent in the OEM design. The result is not only better cooling but also less restriction — meaning the turbo doesn't have to work as hard to push air through, which contributes to improved throttle response and more consistent power delivery across the RPM range.

Installation requires no fabrication. The kit mounts directly to the factory location using the stock mounting points, with OEM-spec connections that make it a true plug-and-play swap. Whether you're running a stock N55, a tuned diesel, or building toward a larger power target, this intercooler provides the thermal headroom to support it — and at 11.7kg, it accomplishes all of that without adding meaningful weight to the front end.
