Mishimoto Performance Intercooler - BMW 135i 335i 335xi N54 2007-2011

This Mishimoto bar-and-plate performance intercooler is a direct-fit upgrade for the N54-powered BMW 335i, 335xi and 135i (E90/E92 chassis). It replaces the heat-soak-prone factory tube-and-fin cooler with a 22% larger core, cast end tanks, and CNC-machined aluminum quick disconnects that mate to the factory intercooler piping. It drops intake air temperatures by 35F and adds 20+ hp while holding factory boost pressure across the core, with no vehicle modification required.
