Performance Koyo Radiator, Mazda MX-5, NA, 89/98, 36mm, (KV060245)

Upgrade your vehicle’s cooling system with the Koyorad Hyper V Series Radiator – VH060245, built for performance, precision fitment, and serious heat control.

Designed for the 1989–1998 Mazda MX-5 NA 1.6L, this radiator is part of Koyorad’s cutting-edge Hyper V-Series, specifically created for vehicles with tight engine bays and high heat demands. It features a 36mm ultra-efficient core and a unique Hyper Fin and Tube Pitch design that delivers maximum surface area for cooling while maintaining airflow in cramped spaces.

With all-aluminum construction, hand-crafted Heliarc welds, and Nocolok brazing, this unit provides the durability and reliability needed for spirited driving and track use. The factory-fit layout ensures a direct bolt-in installation, with provisions for OEM fan shrouds, hoses, and mounts. Automatic vehicles will require an external transmission cooler, sold separately. Pair with a Koyorad Hyper Cap (also sold separately) to push system performance even further.

Key Features:

• 36mm Hyper V-core with optimized fin and tube pitch for exceptional cooling in limited engine bay space

• All-aluminum construction provides high strength and corrosion resistance without excess weight

• Nocolok brazing for solid, vibration-resistant bonding of tubes, fins, and headers

• Billet filler neck offers a tight, secure seal to handle increased system pressure

• Heliarc hand welds ensure a superior aluminum-to-aluminum connection

• OEM-specific mounting allows direct fitment to stock fan shrouds and hoses

• Drain plug included for simple coolant servicing

Installed this in my '94 Miata track build—fitment was spot-on, and temps stayed way more consistent during long sessions. Definitely worth the upgrade over the old stock unit.

Couldn’t believe the cooling improvement. My NA6 runs smoother, even on hot days stuck in traffic. The install was super easy and it bolted right to the factory fan shroud.
