Re: intake fittings
Careful not to over tighten the brass vacuum fitting in the aluminum intake as there's a good possibility of cracking the alum. casting. Just snug, maybe 20-25 in. lbs. and 3-4 threads left showing on the fitting. Nice choice in the Air Gap intake. My guess is 3/8 pipe thread. Oh, definitely use teflon tape.
