Koyorad is pleased to introduce a high quality direct replacement performance radiator for the 2010-2014 Mazdaspeed 3. This radiator features Koyorad's KH Series 25mm radiator core, developed to improve heat dissipation by increasing coolant volume while promoting proper air flow and coolant circulation. In typical fashion, Koyorad engineered this radiator to directly replace the stock OEM radiator for a quick and simple installation. Koyorad has also integrated a 1/8 PT female accessory fitting (supplied with a threaded plug) to accept temperature sensors typically included with most aftermarket temperature gauges. Koyorad’s superior quality, precision hand welds, reliability and uniformity are what have earned Koyorad their excellent reputation in performance radiators worldwide.
