Miata 1990-2005: Radiators, Cooling : Radiator
Complete Miata Radiator Combo with KOYO 37mm ALL Aluminum Radiator, Samco Hose Set, and Koyo Performance Radiator Cap :: 94-97
Combo Special Saves!
Gain 50% capacity over stock Miata radiator! This Koyo Miata radiator upgrade is completely plug and play with all OEM hardware including the stock fans and thicker aftermarket sway bars!
We asked KOYO to make a unit slightly thinner Miata radiator than their monster 55mm core and this 37mm is it. The larger 55mm Koyo Miata radiator is plug and play with all factory hardware but pushes the factory fan housing back enough that they need to be trimmed to fit with LARGER aftermarket sway bars.
But this 37mm Miata radiator fits with all OEM hardware and thicker aftermarket sway bars without having to trim the fan housings. Also very popular with the spec Miata racers because it cures overheating issues for bump drafting drivers without adding as much water weight as the 55mm core.
All aluminum and incredible craftsmanship (not the simple massive fining and large cross tube styles you see on some cheap aluminum Miata radiators which work fine at low speeds but do not cool well at high speeds).
This Miata radiator will give your Miata many years of quality service. Intended for manual transmission only.
Includes our Samco Sport Silicon Hose Update Kit for long lasting performance and great looks. Superb integrity and superior performance reduce the risk of component failure and that enables higher temperatures and pressures to be maintained with complete confidence.
Also Includes our Koyo Racing 1.3 Bar Hyper Red Radiator Cap that raises the cooling system pressure to 1.3 bar to improve entire cooling system flow. The higher pressure cap reduces the chance of air from entering the system compared to the factory cap. It also improves the look of your engine bay.
