*Automatic transmission owners, see notes below*

Specifications:
Full aluminum radiator
Core Depth: 1.400"
Core Height: 13.40"
Core Width: 25.50"
Item Weight: 11.8 pounds
**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.

It holds coolant!

Yes, it does that, of course. Quality seems great but as this is my first one I cannot comment on how long it will/may last. Being all aluminum vs the stock piece which is plastic on top and bottom, I can only assume it’ll last longer. I went through 2 stock radiators, they each lasted about 5-6 years before the plastic would crack. For those curious, I was completely empty upon the install and this took 2.3 gallons to fill. Please enjoy the photo of my blown, stock radiator!

Holly crap fast shipping!

So I was doing a budget build to get my 06 wrx to get her back on the road when I bought a rock auto cheap radiator. Surprise, it failed

In less than 1,000 miles; received a replacement, it failed in 4 days. Did some research and say that IRR had the best prices and reached out to Dane Young to see if they were in stock and how long to get the radiator. My man Dane said they were in stock and would ship same day. Pulled the trigger and the radiator was on my door step in less than 14 hours…… I felt like I was on a high level car show needing this part to make it to SEMA, but nope, just their everyday awesome service. Thanks Dane, if your bosses are reading this, give him a day off paid, cause all my parts are bing order through you guys from now on😎

Solid Radiator

Install and fitment were easy and on point. The fully aluminum build is beautiful and I'm glad to finally have one of these under the hood. Thickness is about 2.5x stock and will definitely cool much more effectively.

Perfect Fit and Finish!

This is my 3rd Koyorad and they ALWAYS fit perfect. The welds are great and they perform flawlessly. If you are on the fence about this one and are looking at the other brands... get this one, the others never fit as well!
