Product Description

The Mishimoto MMRAD-E90-07A Performance Aluminum Radiator is a direct-fit cooling upgrade for 2006-2013 BMW 335i and 2007-2012 BMW 135i models equipped with automatic transmissions and the N54 or N55 turbocharged inline-six engines. Designed as a bolt-in replacement for the factory radiator, this performance unit features a fully brazed dual-row aluminum core with robotically TIG-welded end tanks, delivering significantly improved heat rejection and coolant capacity compared to the OEM unit. Its precision CNC-machined quick-disconnect inlet and outlet fittings allow seamless integration with stock coolant hoses and eliminate the need for modifications during installation.

With approximately a ~35 % increase in coolant capacity and a ~25 % thicker core than the original radiator, the Mishimoto MMRAD-E90-07A enhances thermal performance during spirited driving, towing, or track use - keeping engine temperatures more stable under load. The all-aluminum construction resists corrosion and enduring pressure cycling, and the included magnetic drain plug captures metallic debris circulating in the cooling system for added protection. Backed by Mishimoto's Lifetime Warranty, this radiator offers reliable cooling performance and long-lasting quality for enthusiast BMW applications.
