**Radiator cap not included. The factory radiator cap will more than likely fit. The Koyo SKC-13 radiator cap is compatible and sold separately.

Features:
  • True plug and play installation; No engine modifications necessary and retains mounts for the stock fan shrouds and fans.
  • Hand crafted heliarc welds for stronger enforcement along aluminum connections
  • All Koyorad Hyper V-Series All Aluminum Radiators are Nocolok brazed. (What does that mean? Learn more here: The NOCOLOK® Flux Brazing Process)
  • Developed specifically for vehicles which see extreme heat, are limited in space, and where the factory inlet/outlet locations eliminate the option for a proper N-FLO design.
  • The Hyper V Series radiators have a specially designed fin and tube pitch which significantly increased its surface area while still allowing for excellent air circulation through the radiator.

Automatic transmission owners:

This radiator doesn't utilize an internal transmission cooler. If you wish to install this radiator in your car with an automatic transmission, you'll need to invest in an auxiliary transmission cooler.

Mmhmmm

Replacing the OEM rad with this guy takes away all the uncertainties of running hot. The plastic tanks of the stock one were getting so brittle, every drive was a roll of the dice. 5 stars

Perfect fit, awesome quality.

I replaced my oem radiator for many reasons. It was old, I live in a hot climate, and want to enjoy the occasional spirited drive or track day. This part provides the piece of mind knowing my car has the ability to stay cool. I’ve always had great experiences with these radiators and it fits perfectly without modification.

Worked in my ej205 swapped 01 RS and CLEARED Killer b headers.

As stated above, I have a 2001 Impreza 2.5rs. I just completed swapping it to a USDM ej205 and wanted to run the killer b holy headers I already had on hand. Unfortunately, due to lack of space in the engine bay, the headers TOUCHED the factory WRX radiator I was running in the RS. I took a chance after speaking to a few folks on the forums and went with the KOYO, due to its thinner design. I figured worst case scenario, I can massage a few pieces to make it fit, but I'm this case I got the best case scenario. This radiator actually gave me a good bit of clearance between the headers and the radiator. To be clear, I did have to trim one tab off the bottom, but that was obvious even when looking at the photos online.

Now I have no issues and do not worry about my radiator biting the dust without warning.

I've been driving on it for a week now, and I'm noticing about a 5 degree difference on average and MUCH faster cool down times when the fans kick on. Results may vary as I am running Mishimoto universal fans with NO SHROUD. (A shroud and stock fans may have worked with this radiator, but I prefer to have a little extra clearance in the bay if possible)

I could not be happier with the results AND I get to use the headers people swear I couldn't use due to fitment.
