BMW E90/E92/E93/E82/E88 N54/N55 (06-13) Mishimoto aluminium radiator manual

The Mishimoto radiator E9x manual is an aluminium performance radiator for the BMW 335i (2006-2013) and 135i (2007-2012) with the N54 or N55 engine and a manual transmission. The turbocharged straight six makes plenty of power, but also plenty of heat, especially during spirited driving or on a track day.

Mishimoto builds this radiator entirely from aluminium: a fully brazed two-row core with robotically TIG-welded end tanks and a brushed finish. The core is 25 percent thicker and the radiator holds 35 percent more coolant than stock. CNC-machined quick-disconnect fittings mate with the factory hoses, so the fragile plastic connections of the original are a thing of the past. A magnetic drain plug with Dowty seal collects metal particles from the cooling system.

Installation and delivery

The radiator replaces the original without modification and works with all stock equipment. Mishimoto rates the installation as medium. Check the quick-disconnect O-rings on the coolant hoses for wear and replace them where needed to prevent leaks. Then fill and bleed the cooling system carefully. The installation guide is available below. Lead time: 4 to 7 days.

More coolant, a thicker core and no more plastic connections: that is how your turbo six stays cool on track too.
