Keep your turbocharged straight-six cool with the Mishimoto Performance Aluminum Radiator. The N54 and N55 powering the 335i, 135i, and a wide range of other Bimmers is a mountain of efficient power, but there's the age-old nemesis to speed – heat.

Our design is the perfect upgrade to eliminate rising temperatures. The Mishimoto 335i/135i radiator features all-aluminum construction with TIG-welded end tanks to a 100% brazed aluminum core and CNC-machined quick-disconnect inlet and outlet connections.

The Mishimoto 335i/135i radiator is precision engineered for flawless drop-in fitment while providing a 35% increase in coolant capacity.
This BMW radiator also includes a Mishimoto Magnetic Oil Drain Plug with Dowty seal, which removes circulating metal fragments from the cooling system, providing further engine protection. As with all BMW parts, this aluminum radiator includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship. Say goodbye to the days of broken stock plastic inlet and outlet connections!
