line the pipe up with the throttlebody and with the hole u intend to cut. if its not flush. use ur imagnination and make a template hole with whiteout. give it a small allocation right a bit and a bit further back. u can clear the radiator fan. just sometimes they cut the hole too far forward.
do these kits get the rubber to runalong the cut hle so it dont rub on the pipes?
the clamps that come with the cheaper kits are not the best. u can get the bolt style from hybrid for like $10 a set. much more durable.
next time i install a FMIC either on the 34 or s14a or 33 ill time myself and post up here.
