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!
This 36mm Miata radiator usually fits with all OEM hardware and thicker aftermarket sway bars without having to trim the fan housings (but check clearance to factory A/C condenser and push those brackets forward as needed for clearance). 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 (note these Samco hoses do NOT fit MazdaSpeed version). Includes factory style drain plug.
ALSO INCLUDES our High Performance Samco Silicon Sport Hose Kit. The Samco Sport Hose Kits are designed to replace original equipment hoses and provide superb integrity and superior performance to reduce the risk of component failure, and 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.
BRIAN'S INSTALL NOTES: Sometimes we find the A/C was port installed and placement of the condenser is not always consistent, we just bend the condenser brackets as the easiest way to get the clearance. But you can also unbolt the Condenser and slide it down and then put it in front of the brackets. Be sure you make clearance so your new radiator is not damaged by the condenser!
