fuck the skunk 2 intake mani they are crap. the euro-r accord intake mani's flow almost as good as the skunk 2 and with a little work they can flow more. they cost 225 on hmotorsonline. porting them cost anywhere from 75-150 so pay for the skunk 2 or buy the euro-r. there is some modification needed to make them fit but there are tons of write ups out there telling you how to modify them. as for the head a p&p with new valvetrain, cams, with the intake mani, ported tb, and a header is a great way to make some pretty nice gains in the h22.
