Intercooler for BMW 1 Series E82 (2008-2013)

Unlock the full potential of your turbocharged N54 or N55 engine with the Turner Motorsport Stepped Intercooler. Whether you're running higher boost, track days, or just spirited street driving, this direct-fit upgrade is engineered to dramatically reduce intake air temperatures (IATs) and improve charge air flow for consistent, reliable performance.

Cooler air is denser air, and that means more oxygen per cycle for better combustion and more power. The factory intercooler quickly becomes a bottleneck under increased load or in warm conditions. Turner’s stepped intercooler solves that by offering an 80% increase in frontal surface area and cross-sectional flow, helping your BMW stay cooler and pull harder.

Constructed with high-quality cast aluminum end tanks and a bar-and-plate core, this intercooler delivers superior cooling efficiency and reduced pressure drop, even under sustained high-boost operation. The black powder-coated finish offers a clean, stealthy appearance, while the etched Turner logos add just the right touch of motorsport style.

Perfect for:
E82/E88 135i, E9X 335i/335xi, E84 X135i, E89 Z4 35i/35is

If you're looking to push your turbo BMW harder, the Turner Motorsport Stepped Intercooler is the cooling solution that keeps your engine running strong—pull after pull.

Wagner intercoolers (#200001044) are engineered in Germany to be a superior N54/N55 intercooler than the factory part. With 85% more surface area 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 Wagner has chosen the stepped design to maximize the available surface area in the front end. The step is a thicker bar and plate core with an additional set of rows on top that takes advantage of unused space in the nose. In our eyes, the best intercooler upgrade is one that not only works but also installs with a minimum amount of fuss.

Compared to the stock OEM intercooler:


One of the best features of this kit is how easy it is to install (the easiest we have used to date). It's a direct bolt-on replacement for your stock intercooler - no removing the bumper or modifying brackets or wrestling with plumbing. Core size measures 520 x 210 x150 with a 13.6cm flow rate. 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 E90 E92 335! Fits both N54 and N55 cars.
