The E90 BMW is a great platform for soaking up highway miles during the weekday and taking to the track on the weekend. Aggressive driving results in increased engine temperatures necessitating an effective solution for keeping your straight six cool. Mishimoto has the perfect upgrade, the BMW 335i/135i (Manual only) Performance Aluminium Radiator, to eliminate rising temperatures. The Mishimoto 335i/135i radiator features all-aluminium construction with TIG-welded end tanks to a 100% brazed aluminium core and CNC-machined quick-disconnect inlet and outlet connections. This radiator is constructed from high-quality aircraft aluminium with a brushed finish for the perfect combination of performance and style. The Mishimoto 335i/135i radiator is precision engineered for flawless drop-in fitment while providing a 35% increase in coolant capacity. This 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 our products, this 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!
