hey i am looking for a fmic i was wondering what is the right size to look for an FC? thanks guys

We might need a mod list first. That would be a start to figuring out what you need.

well i got an intake customs turbo back exhaust nothing much but what i am looking for is what size like what size can fit under the bumper or where ever it goes! for fcs

Easiest way, break out a tape measure and now what you are working with, then go shopping.

if it ever stops raining i will go out there and see!

kind of depends on where you're putting the thing, but basically the frame rails are either 27 or 29" apart, and if you're putting the ic under the hood latch you can go about 3" thick and 11" tall. if you put the thing in front of the frame rails then its only gotta fit under the bumper....
