i am curious if there are any mods for the split port intake system? i understand that one port gives air at certain rpms/load and the other is opened at higher rpms...is there a way to have the secondary port open all the time? or would it hurt my performance? any info would be greatly appreciated

 

You can swap the split port upper intake manifold of the windstar which flows runners. I don't think your idea would be any good, no offense. Check vapauto.com for the kit and info about it.

 

x2 with what Shaun said. if you dont want to go the windstar and you dont want to get your upper and lower ported then vapauto sells a upper intake gasket that is supposed to give a bump in performance.

 

thanks for the info! i think ill try swapping the upper and see how that goes. ill let you know how it turns out! thanks again!

 

iirc you will need a tune to go along with the windstar intake. as far as a tuner get one from vmptuning.com
