If you are shooting to be as low as I was, you need a full set of spacers, I never investigated how much hood clearance that I had after adding the spacers.
just cut the hood, no one will notice....but seriously, add the spacers, go to walmart, buy play-doh, make tiny towers of clay on the supercharger (about the height of how much you will add with the intercooler, close the hood, see how much clearance you have.
You might be able to mod the hood beams underneath for an extra 1/2" if you need it.
