[mooktank]

I was wondeing which MAFs are blow through and which are pull through. Im wondering this because im probably gonna get a BOV that vents to the atmosphere and i want a blow through MAF.

ya i am gonna use a BOV on my S/C but i havnt done re-search on a MAF sensor....i want to get a 4" discharge tube and cut a peice out and put it in there with rubber couplers.........and i can put the bov anywhere before the blowthru.....after the S/C.
