Post bascially says everything... can someone pick for me.. or tell me which one gives more gains.. i've searched and read a lot but i still dont know which one is good thx in advance

the gains are minimal on both but go with stillen. It is safer when raining.

^^^ +1

So the STILLEN CAI+ Z TUBE THEN RIGHT??

^yes

Will the stillen+z-tube have a high chance of hydrolocking??! cause i live down at vancouver where it rains pretty much everyday during fall and stuff

Not unless youre car is pretty much submerged ffirst....hahaha. Then in that case your just ****ed anyways.

Stillen all the way. Retains stock intake air flow points and it doesn't cause weird things to happen to the torque like the other one does.

Stillen + Ztube or CF UTR tube.

cant go wrong either way.........id go injen, short ram if your worried about rain
