I saw a new bolt-on in JCwhitney recently called the HELIX PLUS throttle body spacer. It's reportedly proven to impove HP up to 22 , 4 moreMPG , add 25 ft/lbs of torque . My Q. is does anybody have proof it works or is this something we can add to the tornado/turbonator dumpster?

 

I have the airaid throttle body spacer, they're all pretty much the same thing. I'd say the gains are minimal, I don't think it'd be possible to gain that kind of power from these. I do believe thatmy mpg may have gone up alittle bit though.I don't believe there is any proof of those gains out there though.

 

i dont think i would give them 100$ for that, the airaid one looks better
