Koyo S Series Copper Radiator 89-94 Nissan 180SX/ S13 Silvia 2.0L TBO I4 (MT)

S SERIES Copper Core

S Series radiators incorporate the same technology as Koyo's OE aftermarket replacement product line; Moulded plastic tanks but with a copper core in place of aluminum. Due to the excellent heat exchange properties of Copper, Koyorad S Series radiators are a great choice for a light tuned car, when it will not be at speed for extended lengths of time. All Koyorad S Series Radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the stock fan shrouds and fans. S Series Copper Radiators are available for Nissan S13 with SR20DET, S14/S15 with SR20DET, and Honda DC2 Integra vehicles.
