can't tell if we're still discussing cooling or have moved on to fitment so i'll chime in one both.

I have the mishimoto rad behind the greddy front mount and my pfc water temps are around 87 highway. In the city, they are about 90. They would go higher but I have a fan mod so the fans turn on at 91. So it sticks around there.

As for fitment.. no way was that thing going in there with stock ic. I couldn't even put it right vertical.. its on a bit of an angle so it could fit. Must be pretty big relatively speaking.

I don't see how the stock one could outperform the aftermarket ones..

 

I have a koyo rad in my car. The stock IC does fit.

 

Ditto what chewie says...

I have the factory SMIC (currently) and a Koyo n flow, both fit fine together...

I installed the koyo and everything fit perfectly only needed to modify the bottom mounts a little bit to fit the wider koyo . straighten them out and then bend them to fit the koyo . and everything fit perfectly I tried switching the L brackets but then it was to low I put them upright and it went in just fine ..
