I am trying to find what kind, where, or possibly who makes a cold air pipe that is the same size from filter to throttle body. I have a bbk cai on my car now and a 75 mm throttle body and a 75 mm mass air . The problem is the pipe between the tb and mass air drops in size to what looks like smaller than stock. it has a big filter and pipe to the mass air but then small after. i just put a trick flow top end on and since its all 75mm openings this dang pipe is driving nuts. any help would be great!!!
