Product Details

Maximize performance and reduce intake air temperatures on your E90 335d with the Turner Motorsport Stepped Intercooler. Designed as a direct-fit upgrade for the factory intercooler, this high-efficiency unit increases charge air volume and airflow, helping your diesel-powered BMW run cooler, stronger, and more efficiently.

Cooler air is denser air, and denser air means more power. By reducing intake air temperatures (IATs), this upgraded intercooler allows your M57 engine to pack in more air and fuel per cycle, translating to improved performance across the RPM range.

Engineered for performance and durability, the Turner stepped intercooler features cast aluminum end tanks and a bar-and-plate core design, offering superior thermal efficiency and structural strength. Compared to the stock unit, it delivers a 65% increase in both frontal surface area and internal cross-sectional flow, ensuring better heat dissipation and reduced pressure drop. All of this performance comes in a lightweight package under 20 lbs.

Finished in a stealthy black coating with laser-etched Turner logos, this intercooler not only performs but looks good doing it.
