RallySport Direct carries a large selection of Koyo Aluminum Racing Radiators to suit your application for improved cooling performance. These feature all-aluminum construction and are direct replacements for your factory radiator. 

 

DETAILS:

  • All aluminum construction
  • Heli-arc welded for stronger enforcement along aluminum connections
  • Thicker core
  • Precise tube and fin alignment promotes optimal coolant flow and fins with highly efficient heat transfer
  • NoClock Brazing is featured on the tubes, fins, headers, and brackets using a state-of-the-art NoClock furnace which bonds all components to resist damage from vibration, road debris, and the elements
  • Billet Filler Neck is precision machined for durability
  • Fits manual transmission

    NOTES:

    Great Radiator! with 1/8 PT sensor location! 3 months ago
    5out of 5stars

    had a stock rad that was cracked/leaking. got this guy as a replacement and it has been going strong for 2+ years. I am now writing this review so you may not make the same mistake i just did. I purchased the 38mm greddy water temp adapter for my DEFI gauge. HOWEVER, this radiator actually does have a 1/8 PT (BSPT) port located near the top of the radiator for a sensor. 1/8 NPT will not work without modification. Im going to RMA the greddy hose adapter and use the port on the radiator for my sensor. @RSD maybe add that to the notes/description of this product?

    No warranty is risky 1 year ago
    1out of 5stars

    It’s a nice looking radiator, doesn’t really make your car run any cooler, but unfortunately it’s only 2-months old and now leaks. Well...here I am with no warranty, and looking for another radiator. What’s the spot rate on aluminum today? I can’t recommend this Koyorad radiator.

    Beautiful piece, excellent performance.  3 years ago
    5out of 5stars

    I bought this for my 2006 WRX because I had sprung a leak in the OEM radiator. Packaging was excellent, and everything was in pristine condition when I opened it up. Fitment was an absolute breeze, no modifications required, and aesthetically it is much more pleasing than the factory unit. It does an excellent job of keeping my engine cool, even being tuned to Stage 3 @ 19 PSI. Highly recommend.

    QUESTIONS & ANSWERS

    • Q: Koyo Radiator Fitment  Izzy10 months ago

      Will this fit RHD 2006-2007 STi vehicles?
    • Q: Koyo Aluminum Racing Radiator Manual Transmission Subaru WRX/STI 2003-2007   arc131 year ago

      I’m driving a 2006 2.0 JDM WRX with auto transmission and had already installed an ATF cooler so I can install this radiator. I notice that the core depth for this radiator is 1.4 in. Is there other compatible Koyo radiator with thicker core depth? Lastly, what is overall dimensions and weight for the packaging box as I need the info for shipping?
      • 1 of 1 people found the following answer helpful

        A:  You may be able to run this with some modification, although we do not confirm fitment for this on any JDM models. On average this package weighs 15.84.

    • Q: Hello there!  Vargas801 year ago

      Can you tell me if this Radiator fits an automatic Subaru Impreza wagon 2.5i
      • 0 of 0 people found the following answer helpful

        A:  This part is not confirmed to fit your car. If you still install this radiator you will need to install an aftermarket radiator cooler which I personally have done on my automatic vehicles.
