Here are some pictures of a custom intake I built for My 1992 F250 diesel with ATS turbo kit. The intake was originally adapted from a MY1997+ Subaru Impreza intake to fit my former 1993 Impreza LS. I did that work with a hack saw and the addition of a mass air flow (MAF) sensor adapter; For this job I brought out the miter saw with grinding cut-off wheel, which goes through cheap aluminum like what this pipe's made of as if it were nothing, and which makes much better cuts. I then cleaned all cuts with a straight file. I only had to purchase one silicone sleeve as the turbo intake is the same size as the throttle body on the Subaru.
