Wagner intercoolers (#200001029) are engineered in Germany to be a superior M57 intercooler than the factory part. With 50% more frontal 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 un-used 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.
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 20.5"x5.1"x8.25". 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 335d Fits M57 cars.
