Description

RallySport Direct carries a large selection of Koyo Aluminum Racing Radiators to suit your application for improved cooling performance. These are very durable and are direct replacements for your factory intercooler.

Here are the 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

Note that the upper radiator hose may require trimming for proper clearance. 

Early model WRX owners need to verify that their stock radiator has a radiator cap. WRX models without a radiator cap need the 2002 WRX radiator.

Beautiful piece, excellent performance.

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.

Bought this to replace my leaky OEM radiator and it works great. It does cool better and a bit faster like everyone says it does. Haven't ran into any leaky issues yet. Only complaint is the warranty, Only covers defects and... etc etc. So before installation check everything first. So pretty much, upon start up say "good bye warranty"

Koyo Aluminum Radiator. Much better than the stock WRX one, however...
BlackRex 1 year ago
Mine arrived with a dent on the driver's side. Just the side was pushed in about 1/8" - 3/16" closing the last row along a 1 1/2" section. No big deal since it still appears to hold air pressure. The price on sale was very good so I do not mind a small dent as long as it holds water pressure when I install it two weeks from now. The product itself appears to be just right for a street driven WRX/STI. Not too thick and very good air flow with the stock fans applied. I cannot see buying a thicker one for a Subaru unless you will be exclusively on a track.

  • Q: Radiator shroud   ss2ride77251 4 months ago

  • Q: Cores?  Stealthlead 11 months ago

    Answer

    How many cores does this radiator have?


    • A: Part# VH091672, as well as every other all-aluminum radiator we currently offer for Subaru vehicles all have two row cores. VH091672 also has the benefit of having our high density core, which has more fins and tubes per inch resulting in a slimmer radiator but with similar or better efficiency than many three row standard density radiators currently on the market. Let us know if you have any further questions. Thank you.
