How good do the newer f250, f350 intercoolers flow?. Im going to cut one up and use only about 2/3rds of it. So it will basically be a 31x12x2 core. But im not giong to do it if they dont flow that well. btw, paid 40 bucks for it.

 

Not the greatest, but you canfin worse. It's what I'm using. Is this not Johnnyracecar does?

 

It should be good for most applications as a daily driver. Use it and send me the other half

 

Other half? I got 3x 6" from mine.
