Mishimoto BMW 2007-11 335i/335xi/135i 3.0L Black Performance Intercooler

If you're looking to get more out of your 2008-2011 BMW 135i, 335i, or 335xi, especially after adding some modifications, upgrading the intercooler is a smart move. The stock intercooler can struggle to keep up when the engine is making more power, leading to heat soak and reduced performance. This Mishimoto performance intercooler is built to handle those demands.

This intercooler features a bar-and-plate design with a core that's 22 percent larger than the factory unit. That bigger core means it can cool the air charge more effectively, dropping intake air temperatures by about 35 degrees Fahrenheit. Cooler air means a denser charge going into the engine, which Mishimoto says can result in an increase of over 20 horsepower while keeping boost levels consistent with stock. It's constructed with cast end tanks and uses CNC-machined aluminum quick disconnects, so it fits right up with your factory intercooler piping without needing any modifications to your car. The TIG welding ensures solid construction, and this black finish looks sharp behind the grille.

Installation is straightforward, typically taking about an hour, and it comes with Mishimoto's lifetime warranty. If you're pushing your BMW's straight-six engine for more power, this intercooler is a well-built upgrade that directly addresses the limitations of the stock system.
