New Koyo Hyper-V Core Radiator For 02-07 Subaru WRX/STI!

Posted on 11 April 2012

Koyorad | Koyo is proud to introduce a new and improved all aluminum Race radiator for the 02-07 Subaru Impreza WRX/STI w/ Manual Transmission (Koyorad part number VH091672). Koyorad’s revised version replaces the 53mm version with their new 36mm “Hyper V” core. While being a thinner core at 36mm it is equally as effective since designed with a much higher fin density. This improved version saves weight, improves space and air circulation to the engine and other components. Integrated into this new design is a female 1/8″ NPT fitting (supplied with a threaded plug) which accepts temperature sensors typically included with aftermarket temperature gauges. Koyo designs and manufactures each radiator with precision; therefore this is a direct-fit performance replacement for the stock OE plastic/aluminum radiator for a quick and simple installation with no modifications.

Koyorad quality is a direct result of their privately owned factories which allow Koyorad Japan to oversee each stage of radiator production. This ensures that quality is never sacrificed for quantity. Each Koyo all aluminum radiator core is hand assembled, Nocolok brazed, then TIG welded by hand with the finest aluminum available. These are just a few characteristics that have earned Koyorad Radiators their excellent reputation in performance radiators worldwide.

  • OE Specific mounting and direct fit
  • Mirror polished finish
  • Nocolok-R Brazing
  • Precise Tube and Fin alignment
