Most excellent upgrade

I upgraded my radiator as I was approaching 85k miles and the plastic on my old radiator was beginning to get brittle. Great quality. I’ve noticed that the car runs a little cooler but drops temp much faster after pulls or aggressive driving. Looks great in the engine bay. Don’t forget to order the cap as well.

I should have upgraded sooner

Purchased this rad after my OEM plastic separated from the aluminum. I would normally run 205° with the OEM. But with Koyorad, I'm around 190°. CRAZY difference!

Worked perfect

Ordered this due to my 2019 sti temps going up with this AZ heat. Temps were upwards of 226f on the freeway at about 3k rpm. Now i can cruise upwards of that no problem and temps stay typically stay under 210f
