Koyo Aluminum Performance Radiator

The Koyo Aluminum Performance Radiator line (sold under the Koyorad name) gives you an all-aluminum upgrade over a stock plastic-tank cooling system. It suits street, track and hot-climate driving. Koyo has more than 50 years of experience building OE replacement radiators. It has applied that experience to a lightweight, high-performance racing radiator line.

Key Features:

• All-aluminum construction: the core and end tanks are aluminum. This replaces aging OEM plastic-tank designs.
• Nocolok brazing: the brazed core is built for strength and consistent quality.
• Hand-assembled, precision-welded build: the radiators are hand assembled and TIG welded. They are pressure tested during manufacturing.
• High-efficiency core designs: the line uses cores with a fin and tube pitch that increases surface area while still allowing good airflow. This helps manage engine temperatures under demanding conditions.
• Application-specific design: these are not universal-fit parts. Designs are made to fit specific applications and are intended as direct-fit, drop-in installations. Many use the factory fan shrouds and mounting points.
• Japanese engineering and quality control: Koyo oversees each stage of production in its own facilities.

Koyo radiators are a good choice if you want better cooling reliability and a lighter, more durable radiator than the factory unit. Select the child item that matches your application to get the right part number.
