Engine radiator MISHIMOTO or Koyo

Koyo Radiator A2807. Great brand and very affordable.

My opinion koyo rad. But any with the heart symbol are favorites.

I’ve also personally had good luck with mishimoto.

It’s got an actual Koyo radiator which is a good sign.

My only recommendation after testing several different radiators is to go with Koyo.

My '09 had the bad number, so I bought a Koyo radiator and spent an afternoon swapping it all. That was ~6-7 years ago.

Koyo radiator is the move, it’s all aluminum, no plastic to worry about, the drain plug is legit and there’s a port to add a coolant temp sensor if you want gauges. It has an extra row for better heat exchange and dissipation my only complaint is there’s no aftermarket specific dual cooling fan set up which I feel would do wonders for cooling the engine bay at idle .

As for highway driving (when the high speed airflow takes over) I saw little to no difference with my OEM vs Mishimoto All-aluminum radiator. Hot day, w/ and w/o AC temps push 220F easily.

I have a mishimoto one and the Fitment is god awful would have gone with csf or koyorad if I did it again

I have Mishmoto ( dont recommend) on my 2016 wrx in Arizona at 110 days w the Ac on it runs at 190-197 on the streets. While on the freeway its at 215 avg while cruising at 80mph. Been on my car since 2017 I think. But this was before CSF and whatnot came around. Can’t wait to save up and switch.
