The Koyo VH091163 is a high-quality all-aluminum performance radiator engineered for 1999-2001 Subaru Impreza RS, Outback, and Impreza L models, as well as 1999-2002 Subaru Forester 2.5L with manual transmission. This direct-fit replacement radiator features Koyorad's advanced 36mm dual-row Hyper V-Core technology, designed to deliver superior cooling performance over the factory plastic and aluminum radiator.

Key Features:

• 36mm dual-row high-density Hyper V-Core construction for enhanced cooling capacity
• All-aluminum design with Nocolok™ brazed core and precision hand TIG-welded tanks
• Specially designed fin and tube pitch that significantly increases surface area while maintaining excellent airflow
• Direct bolt-in replacement with no modifications required

• Superior heat dissipation for high-performance, track, or rally applications

The Hyper V-Core series represents Koyorad's latest advancement in performance cooling technology, specifically developed for vehicles operating in extreme heat conditions or limited-space environments. Each radiator core is hand-assembled in Koyorad's privately-owned facilities and undergoes rigorous quality control to ensure precision fitment and long-lasting durability. This radiator provides 20-30% more cooling efficiency compared to OEM units, making it ideal for modified engines, spirited driving, or demanding conditions where reliable cooling is critical.
