Koyorad: Alloy Radiator: Rad. Sylvia/180/200/240SX Man. 10/93-11/94
Upgrade your Nissan Silvia S14/S15 (1993–2002, SR20DET manual) with the Koyorad KH020369 Alloy Radiator. Featuring a thick 48 mm HH-Series Hyper-Core, this performance radiator delivers up to 35% more cooling capacity with ultra-high fin density for superior heat transfer during spirited driving or track use. Precision-built in Japan using Nocolok brazing and hand TIG welding, the radiator ensures exceptional strength, leak-free reliability, and corrosion resistance. Its N‑Flo dual-pass coolant routing increases coolant dwell time, improving thermal performance in low airflow conditions. Designed as a plug-and-play upgrade, it retains OEM mounts, fan shroud, hoses, and includes a billet filler neck plus a 1/8″ NPT accessory port—no modifications required
