I am making a CAI and the MAF is 3.5 Inches. My question is can I use a 3in pipe to go from the maf to the filter, or will this be too small?
Thanks

do 3.5 the whole way or your homeade tubing really wont make much of a difference from stock.

well when i bought the car all it had was a filter on the end of the maf. So I am not really expecting much of a great performance increase. So your saying i should go with 3.5 and not 3?
Thanks

it would be bottle necking it. the whole system should be the same diameter or you wont gain the whole benefit of having a bigger MAF. the MAF might be bigger, but it wont matter unless you have the whole intake the same size.

in addition to the homeade CAI being the same size, you should probably go with a 65mm throttle body if you havent.

ya 5.0 mustang magazine had a tb install taht was a 65mm and they said that even though it was a completely stock except for exhaust, engine, they could actually feel a difference wehen driving. So i say go 65mm as i think stock is 55mm not sure though.
