Description

Koyo Hyper V WRX Radiator – 36mm Hyper V-Series (VH091672)

The Koyo Hyper V WRX radiator is the go-to cooling upgrade for Subaru WRX and STI owners chasing performance without sacrificing engine bay space. Whether you’re daily driving through NZ’s unpredictable weather or tracking your turbo EJ, this radiator keeps temps under control with a compact 36mm core—built for modern engine bays where space is at a premium.

Using Koyorad’s latest Hyper V-Series core technology, this high-performance radiator features a uniquely engineered fin and tube pitch that significantly improves surface area and airflow. The result? Serious cooling power without a bulky design—ideal for those tight WRX and STI engine bays where airflow and fitment are often compromised. The Koyo Hyper V WRX radiator is also a true drop-in replacement, requiring no cutting or modding to fit stock fans, hoses, and mounts.

Crafted in Koyorad Japan’s privately owned ISO-certified facilities, every radiator is hand TIG-welded, Nocolok brazed, and constructed entirely of high-grade aluminium. This quality control ensures long-lasting durability, thermal efficiency, and trusted performance for both track and street use.

Features and Benefits

  • 36mm Hyper V-Series Core – Compact core with advanced fin pitch delivers maximum heat dissipation in tight spaces.

  • All-Aluminium Construction – Lightweight, corrosion-resistant, and built to last.

  • Nocolok Brazing – Adds vibration resistance and structural strength by bonding fins, tubes, and headers in a furnace.

  • OE Fitment Design – Bolts directly into factory mounts, hoses, and fan shrouds with no modifications.

  • Precision Tube and Fin Layout – Boosts cooling performance even under high-load driving conditions.

  • Hand TIG-Welded – Each unit is welded by hand for the strongest aluminium-to-aluminium joints.

REVIEWS

J.S.
Installed this Koyo Hyper V WRX radiator in my ’06 STI and instantly noticed lower temps and no more overheating during spirited runs through the Coromandel. Fitment was bang on.

Didn’t want to cut anything on my GDA WRX, and this dropped straight in. Temps are down, and it looks mint in the bay. Can’t beat Koyorad quality.
