Performance Koyo Radiator, Mazda MX-5, ND, 2015+, 25mm, (KS063152) (NEW)
Description

Upgrade your Mazda’s cooling system with the Koyorad Hyper KH Series Radiator – KH063152, engineered for lightweight efficiency and track-ready thermal control.

Designed for the 2015+ Mazda ND MX-5 2.0L, this radiator features a 25mm high-density all-aluminum core specifically built for modern compact engine bays. Its slim, lightweight design increases coolant volume and improves airflow, keeping temperatures stable even during high-rev, high-heat scenarios on the street or track.

The HYPER KH Series construction includes precision Nocolok brazing and expertly hand-crafted Heliarc welds, ensuring exceptional strength and vibration resistance. A billet aluminum filler neck enhances durability and sealing under pressure, and the included drain plug makes maintenance clean and simple. Installation is quick and direct thanks to OE-specific mounts for fans, hoses, and factory hardware.

Automatic models require an external transmission cooler. For maximum pressure control and performance, pair it with the optional Koyorad Hyper Cap (sold separately).

Key Features:

  • 25mm high-efficiency HYPER KH core boosts cooling capacity without sacrificing weight or airflow

  • All-aluminum design resists corrosion and reduces weight

  • Nocolok brazed construction creates strong, vibration-resistant bonds

  • Billet filler neck ensures a tight seal under high pressure

  • Precision Heliarc welds deliver strength and long-term reliability

  • OEM-specific mounting points allow a direct bolt-in install with factory fan shrouds

  • Drain plug included for quick maintenance

  • External transmission cooler required for automatic vehicles

Swapped this into my ‘19 ND Club after tracking issues with rising temps. Fitment was perfect and temps are now rock solid. Top-tier craftsmanship.
