Discover exceptional cooling performance with Koyorad's all-new radiator designed for the 1988-1999 BMW 3-Series/M3. This radiator features the advanced 48mm "HH" Series core, boasting an ultra-high fin density for optimal heat transfer. Each Koyorad radiator is meticulously designed and manufactured with precision, serving as a direct-fit performance replacement for the stock OE plastic/aluminum radiator. Installation is a breeze, requiring no modifications. Koyorad has gone the extra mile by integrating a 1/8” NPT female accessory fitting (supplied with a threaded plug) to accommodate temperature sensors commonly used with aftermarket temperature gauges.

The hallmark of Koyorad quality stems from their privately owned factories, enabling Koyorad Japan to oversee every facet of radiator production. This unwavering commitment ensures that quality is never compromised for quantity. Each Koyo all-aluminum radiator core is hand-assembled, Nocolok brazed, and meticulously TIG welded by hand, using the finest available aluminum. These attributes have solidified Koyorad Radiators' stellar reputation in the world of performance radiators.
