well you can use a single cam maf because there pretty much identical. plus my stock sr plug works with the maf. and this might sound weird but is there something in the maf or wrapped around it that keeps out, outside interference?, and i have pressure tested the front mount, many times. and i constantly fix it, but it just happens over time, like just driving the car makes it move and run like shit. im going to order new couplers and clamps.
