hey guys im fairly new to the whole tuning scene so any and all help is really appreciated.

my question is one i see that seems to come up a lot (so i apologize for the redundancy), but i cant seem to find any direct hp gain information on this issue

a lot of people seem to choose the ztube/pc combo over the cais and ive gotten the impression that the pc/ztube is louder and what not, but i want to know which option results in more hp gains

ive already ordered a 5/16 spacer and i want to do an intake upgrade next and since the price between the two isnt something im too worried about at this point i just want to go with the one that results in more gains

the dynos on the injen cai seem to be pretty impressive (ive read about over 12-14 gains).

again any and all help is extremely appreciated and thanks in advance!

 

i think between the two you wouldnt even feel the hp differents...but ppl get the z-tube/popcharger combo mostly for the sound it makes and that 12-14hp gain is only true if you put mad JDM stickers on with it hahahahaha jk

 

no real gains either way, pick whichever looks the shiniest

 

just get the ztube/popcharger
