You would benifit going from a smic to this fmic. It's not huge. It is big, but your knock counts will decrease becasue your charged air will be significantly cooler. And you'll beable to run more then 3 times at the track without having to shut down for a half an hour.
You will have to do some cutting on the bumper for the bends to fit onto the intercooler, and you will need to relocate your overflow tank. Big deal. You can just buy a 1g bov from one of us or online for $20..
