    What else can I say that hasn’t already been said? I’ve run this for a little over 2k miles w a few bolt-on mods and a modest tune w no issues. Installed easy!

    Good oem replacement  12 months ago
    4out of 5stars

    Perfect fit just like the original. Nothing special about this product if you need a replacement for your busted radiator this is a good match for the price. Only bad thing is drain valve on bottom was broken when it arrived Definitely inspect the radiator before instal.

    Great service and Parts 1 year ago
    5out of 5stars

    Bought this after my OEM radiator developed a crack near cap. The part was almost exact match to Stock OEM radiator and was a breeze to swap out with this Koyo OEM replacement radiator. I have had this in my car for over 2 years now and it is going strong.

    QUESTIONS & ANSWERS

    • Q: limits  carl1 year ago

      Will this hold up to a heavily built engine or do I need to go towards the aluminum racing radiator?
      • 0 of 0 people found the following answer helpful

        A:  I would recommend going to a full aluminum radiator if you are hard on the car or plan on tracking it. This one would work: https://www.rallysportdirect.com/part/radiators/koy-vh091672-koyo-aluminum-racing-radiator-manual-transmission

    • Q: Strength  soonbedead1 year ago

      I'm on e85 and just blew my second oem radiator. The first was the original radiator that came with my car and blew after i started adding power and the second one I got used from a friend just blew after switching to e85. Will this hold up better than an oem one at 360whp?

        A:  This part should work perfectly as a replacement.

    • Q: Radiator seam's are leaking!!!   AdamSubaru1232 years ago

      I recently bought this radiator off you guys (September 2018) and the seams are already leaking!! I see that there is a 18 month warranty, how do I return and/or get a new one shipped! I am extremely disappointed as I did not plan on it leaking expensive coolant all over the driveway...again!
