Koyorad HH021568 – 48mm Series Radiator | Nissan 350Z (2003–2006)

Application: Nissan 350Z (2003–2006) | Part Number: HH021568

The Koyorad HH021568 is a high-performance 48mm core radiator engineered specifically for the Nissan 350Z (2003–2006). With a significantly thicker core than the OEM unit, this radiator delivers substantially improved cooling capacity — ideal for spirited street driving, track days, or any application where heat management is critical.

Constructed from lightweight, high-conductivity aluminium alloy, the HH021568 features Koyorad's precision-brazed construction for superior durability and thermal efficiency. The all-aluminium design reduces weight compared to OEM copper/brass units while dramatically improving heat dissipation.

Designed as a direct OEM replacement, the HH021568 bolts in without modification — retaining all factory mounting points, hose connections, and fan shroud compatibility for a clean, hassle-free installation.
