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.

If you're looking to get the most out of your E90 335d, the Turner Motorsport Stepped Intercooler is a must-have upgrade for your turbo diesel intake system.

BMWs turbocharged S55 engine uses a water-to-air charge air cooling system, with a front-mounted heat exchanger responsible for heat dissipation. Unfortunately, the factory single-row, 27mm core design is quick to heat soak under high load, leading to excessive intake air temperatures and potential limp mode conditions especially on modified or track-driven cars.

To solve this issue, we've developed a drop-in upgrade over the factory unit. Engineered for durability and maximum cooling efficiency, this heat exchanger is a must-have for high-horsepower street builds, spirited canyon driving, and extended track sessions. Built from TIG-welded 5052 aluminum, our design eliminates the factory plastic end tanks one of the systems most common failure points. Each heat exchanger features CNC-machined billet aluminum hose connections, mounting flanges, and brackets for perfect OE fitment and trouble-free installation.

By replacing the OEM 27mm single-row core with a robust 35mm dual-row design, this heat exchanger dramatically increases both cooling capacity and surface area. Frontal area jumps from 307mm to 475mm, resulting in a 100% increase in coolant volume and significantly improved heat-soak resistance. The outcome? Lower, more stable charge air temperatures that help your S55 deliver consistent, reliable power on the street or at the track.

Forge's larger intercooler installs with no cutting or even removal of bumpers.

After a quick and simple install, you can expect temperature drops of 25 degrees Celsius. Lower temperatures leave room for more power and less heat soak thanks to a larger cooler charge. This intercooler features a bar and plate design core, featuring overall larger dimensions that improves cooling ability in comparison to the stock intercooler.

This product fits the following BMWs:
2014+ F22 M235i M235iX
2012+ F30 335i 335iX 
 

When modifying the car and increasing boost, installing an upgraded intercooler is essential to keep the engine computer from restraining boost as temperatures climb. The stock air-air intercooler is quickly overcome with heat and can't keep the intake air cool enough. If it's too hot the engine computer will reduce power to safer levels. A Dinan intercooler is much larger than stock, providing more surface area for cooling air to pass through. Even heat soak at low speeds is reduced, making this a worthwhile addition even for stock or mildly tuned engines. The E92/E93 335i Dinan intercooler is 93% larger than stock but is a direct replacement with only minor trimming of plastic undertrays required for installation. The factory charge piping in and out of the intercooler is re-used.
