Product Details

Koyorad 36mm Hyper Core Aluminum Racing Radiator  Honda S2000 2000-2009


Koyorad is proud to introduce a newly revised aluminum radiator for the Honda S200.  This is a new and improved all aluminum performance radiator for the AP1 and AP2 S2000 specifically (which replaces Koyorad part# R2344). Koyorad is always making improvements to their products and have revised their 53mm thick standard core version with the new 36mm "Hyper" core.  The revised core has an increased fin and tube count for improved heat dissipation. This decrease in core thickness reduces overall weight while increasing air circulation and engine bay space. Koyorad has also integrated a female 1/8 PT port (supplied with a threaded plug) which accepts temperature sensors typically included with aftermarket temperature gauges. Koyorad designs and manufactures each radiator with precision, offering a direct-fit performance replacement for a quick and simple installation. Racing series radiators were made for manual transmission only, however with a separate automatic transmission cooler; one can use the Koyo Racing Radiator with automatics for increased cooling capacity.



  • 36mm “Hyper” Core
  • Increased tube and fin count
  • Direct fit performance replacement radiator
  • Nocolok-R Brazing
  • Precise Tube and Fin alignment
  • Billet aluminum filler neck
  • Includes AP1 to AP2 fan switch adapter
  • 1/8 PT female accessory fitting with plug

Product arrived in France in pristine condition. Perfect fit for my Honda S2000 MY2006 (This radiator fit all MY 00-09 S2000). Cooling is now far more efficient than before (core of the Koyo is 3 times thicker than the stock one) and the finishing of the product is top notch. It's basically a straight swap from the stock Denso radiator. You will also need 8 litres or 2.64 gallons of Honda coolant to fully refill the cooling system. DO NOT FORGET to order the right radiator cap for the radiator because it isn't included. The reference of the radiator cap is:
