Performance Koyo Radiator, Mazda MX-5, NC, 05/14, 36mm, (KV061885)

Upgrade your vehicle’s cooling system with the Koyorad Hyper V Series Radiator – VH061885, built for space-constrained engine bays and serious heat control.

Designed for the 2005–2014 Mazda NC MX-5 2.0L, this radiator features a 36mm high-density aluminum core with Koyorad’s proprietary Hyper Fin and Tube Pitch layout. It’s purpose-built to maximize cooling efficiency in tight spaces while maintaining optimal airflow—even under extreme driving conditions or high under-hood temps.

The all-aluminum two-row construction, Nocolok brazing, and hand-crafted Heliarc welds offer exceptional durability and long-term performance, while a billet filler neck ensures proper sealing under pressure. Installation is quick and clean with OEM-specific mounts and factory hose compatibility. Automatic vehicles will require an external transmission cooler, and optimal pressure performance can be achieved with an optional Koyorad Hyper Cap (sold separately).

Key Features:

• 36mm ultra-efficient Hyper V-core increases coolant volume and airflow efficiency in limited engine space

• All-aluminum construction reduces weight and resists corrosion in demanding conditions

• Nocolok brazed components provide a vibration-resistant, high-strength bond

• Billet filler neck for a precise, leak-resistant seal under high pressure

• Hand-crafted Heliarc welds deliver superior aluminum bonding strength

• OE-specific mounting points ensure easy, direct bolt-in installation with stock fan shrouds

Installed this in my ‘07 NC and it’s been a game changer. Temps stay stable even during long canyon runs, and the fitment with the OEM shroud was spot on. Highly recommend if you're serious about performance.
