Product Details

Koyo's "R" Series aluminum radiators feature a 53mm (2 1/16 in) thick, all aluminum core brazed to polished aluminum end tanks for a show quality finish. Koyo uses state of the art Nocolok Brazing Furnace to bond all of the radiator brackets, headers, tubes, and fins, creating high quality "indestructible" radiator. All aluminum end tanks are hand crafted using the latest Heliarc Soldering technique for the most reliable connections, then polished to a mirror finish. Over 60 applications are available for Koyo "Racing" series.

All Koyo Racing series radiators have "OE Specification" mounting location for stock mounting without major modifications; however we recommend using aftermarket electric fans for the best results. Koyo Hyper Radiator Caps are also available to increase your cooling system pressure to 1.3 bar for increased cooling capacity. 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.

  • Nocolok Brazing
  • OE Mounting Specifications
  • Heliarc Soldering (hand crafted)
  • Tube and Fin Alignment
  • Koyo Mirror Finish

 

NOTE: Discontinued please see Koyorad HH020252N for updated model.

Pair this with a GKtech engine fan and proper shroud set up (I am also using PSM HMIC) and everything else pails in comparison to this amazing design. With the typical over heating problems that you get when using the Nissan sr20, It is definitely worth it to spend the little extra for the N flow design. look up how it works, It is very innovative.

Excellent quality! I've yet to see my S13 SR20 coolant temps go over 195 degrees with this radiator during normal driving. There may be lots out there now that looks like this one, but this is the one I have and this is the one I know works!
