Koyo Half-Size Aluminum Radiator

Part #: HH032412

Overview

The Koyo Half-Size Aluminum Radiator is a high-performance cooling component designed specifically for Mitsubishi Evo 8 and Evo 9 models from 2003 to 2006. This radiator is engineered for racing applications, including drag racing, small track events, and short-duration race vehicles, where optimal cooling efficiency and lightweight construction are critical. Its compact, half-sized design helps reduce weight and improve airflow, supporting the demands of high-performance driving. Built with durability and reliability in mind, this radiator ensures your engine remains within optimal temperature ranges during intense driving conditions, helping to prevent overheating and maintain consistent performance.

Key Features

This radiator features application-specific mounting locations for all fan shrouds, inlet/outlet hoses, and top/bottom mounting pins, facilitating quick and straightforward installation. Each unit is individually Heliarc welded by hand, creating a strong, durable aluminum-to-aluminum bond that withstands the rigors of racing environments. The all-aluminum construction ensures excellent heat dissipation, corrosion resistance, and lightweight performance. Its design prioritizes efficient cooling and ease of installation, making it an ideal upgrade for race-focused Mitsubishi Evo owners seeking reliable thermal management.

Construction & Design

The radiator’s construction emphasizes high-quality aluminum materials, with precise hand welding to ensure structural integrity and longevity.
