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.

Key Features:

Designed specifically for the E90 335d (M57 engine)
Cast aluminum construction for durability
High-efficiency bar-and-plate core
65% increase in frontal and cross-sectional area
Significantly lowers IATs for improved power and reliability
Reduced pressure drop for more consistent boost delivery
Lightweight design – under 20 lbs
Dimensions: 520mm wide × 200mm tall × 150mm deep
Direct bolt-on installation – no modifications required
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.

Engines make more power when you're able to move as much air and fuel as possible through them. However, air density is just as important as air volume. Cooler air is denser air, so in addition to keeping your engine cool, it's important to make sure that your intake charge is as cool as possible. Turner Motorsport's upgraded intercooler works to reduce air temperatures with a bare minimum of pressure drop. Less pressure drop means less restriction, and a turbocharger that doesn't have to work as hard. This results not only in a longer service life for your turbocharger, but a substantial increase in performance as well.

The stepped design increases volume and surface are in a limited space by adding an additional smaller core at the top of the intercooler. Both cross sectional area and frontal surface area are increased by a whopping 56%, with a design that still weighs under 20 pounds. On the stock intercooler, the temperature differential between the inlet and outlet sides of the intercooler represented a 95 degree drop. With the Turner Motorsport intercooler, that drop was increased to a chilling 140 degrees. The dyno results don't lie: as a bolt-in upgrade, expect gains of 18 wheel horsepower and 10 lb/ft of torque. With a tune and supporting modifications, further gains are possible, up to 36 horsepower and 28 lb/ft of torque.

This cast aluminum intercooler features an attractive, easy to clean matte black finish, with etched Turner logos on the front and bottom. If you're looking for the ultimate cooling system upgrade for your turbo BMW, look no further.

Wagner Competition intercoolers (#200001071) are engineered in Germany to be a superior N20/N55 intercooler than the factory part. With 85% more surface area and 90% more volume than the factory IC the Wagner-designed kit is much more efficient. And that helps maintain your boost levels and performance! The factory intercooler is quickly overcome with heat and that leads to a loss of boost and performance. Factor in greater boost levels and other modifications and the more heat soak will put you out of the running. The solution is an intercooler with more capacity for cooling and the best intercooler upgrade is one that not only works but also installs with a minimum amount of fuss. 

This competition intercooler kit utilizes a tube fin center core unit, for cooler temperatures and less pressure drop. This is for ideal for owners who are going to install a tuner, build a competition car or operate in hot climates. This can be used on the street, track, and for an everyday driving and will allow cooler temps and more air flow through the core! 

Compared to the stock OEM intercooler:


One of the best features of this kit is that it's a direct bolt-on replacement for your stock intercooler - no removing the bumper or modifying brackets or wrestling with plumbing. Wagner has also engineered their end-tanks in aluminum instead of the factory plastic, which is much more durable over the long term. The CAD and FEM process also allows them to design their cooler internals without any bottlenecks or restrictions. This is just the best all-around intercooler upgrade we have seen for the F30 335! Fits both N20 and N55 cars.

BMW’s 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 system’s 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.
