Well the tap is 3/8-18 NPT and the bit i used was 9/16" They say to use a 37/64" bit but good luck finding one of those. 9/16" is very close and works fine.
NPT is National Pipe Thread and it's actually tapered.

x2 yea do that. i used the 9/16" bit aswell and the the same tap. worked just fine
I was gonna tap mine myself, but the drill bit and tap was nearly $20. So I had a machine shop do it for $20, which was well worth it, plus i didn't have to sweat messing it up.

Yeah the parts were expensive but now I have the tools.
Why do you need to drill for it though, I thought foxes already had it in the lower intake.
you talking to me? I got an explorer intake yesterday outta the j/y(pick and pull opened about 12 miles from my house
