The E90 BMW is a great platform for soaking up highway miles during the weekday and taking to the track on the weekend. With some minor modifications, the straight-six is capable of producing substantial power. Added power will push the limits of the stock charge air system, necessitating an upgrade for the stock tube-and-fin intercooler, which is prone to heat soak. Mishimoto has developed a highly efficient bar-and-plate BMW 335i intercooler engineered specifically for the BMW 335i/335xi/135i.

This BMW intercooler is a direct-fit unit and features a 22% increase in core volume while requiring no modification to your vehicle. This cooler is constructed with cast end tanks and precision CNC-machined aluminum quick disconnects for use with the factory intercooler piping. The BMW 335i intercooler reduces intake temperatures by 35°F (19.45°C) and provides an increase of 20+ hp while retaining factory boost pressure across the core.

This 335i intercooler also features precision TIG-welding and is available with a silver or black finish. With a one-hour installation, substantial power and temperature benefits, and a Lifetime Warranty, the E90 BMW intercooler is a must-do upgrade for any stock or modified BMW.
