Is anyone running a Koyo or Fluidyne radiator with an M2 C/F intake? Have the intake, need a radiator, and I'm thinking the larger radiators might fill the small gap beside the original radiator where the M2 draws it's fresh air. Any insight is appreciated.

You won't have a problem. The Koyo is more difficult to install, fwiw. Both rad.s are great.

Good luck with your installation.

 

The aftermarket radiators are thicker, not bigger in length or width. The only problem you may have would be that the thicker radiator and higher mounted upper hose push the nose of the intake up a little bit. This varies by car.

 

if you are going with koyo think ahead of what other mods you will do in the future if any. I'm strictly talking about IC's. For example the Koyo and the PFS SMIC have issues on fitment when using them both.

 

I have a PWR radiator (basically the same as a Fluidyne) with an M2 airbox and encountered no fitment or clearance issues whatsoever between the two.

 

I have the Koyo radiator and the RE CAI (knock-off of the M2). No fitment problems between the two. However, there is a known fitment problem between the Koyo and a larger intercooler. You'll need to drop the Koyo down. Search, and you'll find several threads on this, to include step-by-step instructions on how to reposition the brackets.

BTW, I have a large ASP ic for sale,

 

I had to shim my stock intercooler so the duct wouldn't contact the fans, but haven't had any issues with the intake.
