Koyo Aluminum Race Radiators provide 20% to 30% more cooling than standard radiators, handle high revving, high performance motors, perfect for turbo engines.
Made from aircraft quality aluminum and Heli-arc welded, cores are NOCOLOK-brazed.
The Evo 4-6 model (pictured) puts the upper coolant hose in a different location than the 7-9, creating extra room for exhaust manifolds.
