  1. Awesome Product!!

    I picked one up to replace the leaking oem radiator in my higher mileage s13. Easy install and great results.

    Amazing quality and price, highly recommended! I will definitely be buying another soon for my s14 as well!!

  2. Best radiator ever :)

    Posted by Shealynn on

    I recently wrecked my S14 and bent the ever living shit out of the radiator. put it back in, works like a champ. Still holds water and pressure just fine. Was kind of skeptical of getting is because of it not being "Name Brand", but i really like how it has held up. ISIS makes amazing quality products and I recommend them to anyone.

  3. prevent a meltdown

    dont rely on that factory metal-plastic radiator to keep your ride cool during an event or tearin up the high winding rb20 loves it.great fitment and price.

  4. Extremely Effective!

    Had the Radiator for about 6 months now and i have ZERO complaints. Keeps the engine temps down and as I'm driving i can watch the engine temp actually get lower/cooler. Absolutely no leaks and with the ISIS electric fans, this setup is perfect.

  5. Very effective!

    I'm currently using this radiator in my S13 RB25DET swap. It preforms to the "T". I owned a mishimoto before, but I Prefer the ISIS radiator because of the extra mounting brackets on the bottom. It seemed to be a better fit also. Strongly Recommended!!
