Koyo 1990-1997 Mazda MX-5 Miata 1.6/1.8L (MT) Radiator

Koyorad VH060245 – Hyper V‑Core Aluminum Racing Radiator for 1990–1997 Mazda Miata NA/NB (Manual Transmission)
Maximize cooling on your classic Mazda Miata with the Koyorad VH060245 Hyper V‑Core radiator. Built from all-aluminum, this direct-fit radiator delivers performance and reliability where it counts—especially for enthusiasts who demand more from their NA/NB chassis.

Engineered with a two-row, high-density 36 mm Hyper V-Core, it dramatically increases coolant volume and heat dissipation while keeping overall dimensions slim to fit with stock hardware and tighter engine bays.

Precision TIG-welded tanks, Nocolok‑brazed core, and triple pressure testing ensure durability and leak resistance under thermal stress and vibration.

Designed as a plug-and-play upgrade, it retains OEM fans, shrouds, mounts, and radiator hoses—installation is straightforward and hassle-free.

Made in Japan under Koyorad’s strict quality control, delivering the premium build that racers and weekend drivers rely on.

Customer feedback highlights exceptional build quality, fitment, and ease of installation, often noting that even stock fans align perfectly with the new radiator.

Features & Benefits:

• Direct bolt-in for 1990–1997 Mazda Miata (1.6L/1.8L, manual only)
• 36 mm Hyper V-Core enhances airflow and cooling without bulk

Why It’s Worth It:

Older Miata radiators are prone to overheating under spirited driving or track use—especially in tight engine bays. The VH060245 fights that problem with ~20–30% better cooling performance, lower operating temps, and improved consistency when under load. Whether you're daily driving, autocrossing, or racing Spec Miata, this radiator adds both function and form to your 90's Miata.

Fits:
