"SpiralMax" or "Tornado"

I was wondering if these products actually work. I have an '03 GT and saw an advertisement for spiralmax on this website. Are they worth the money, $50-$90, if they do work, which brand should i get? And is there an increase in HP? Thanx for the help.

everythign i have seen is that if anything they just block air in the intake

no they dont work its a waste of money.

:iagree:

true waste of money, my dad got it he didnt feel any diffrence nor gas

Its a restriction in air flow system. On an EFI motor, you want as little restrictions as possible.

Don't waste the money.

thanx for the advice.

np man thats what everyone in this fourm is here to help ya
