Anyone ever used this and is it worth it?

What is spiral max?

Its a circle that spirals the air like a tornado, to get better combustion, it goes in the tube after the filter

Most think that they are a waste of money. But if you want to test one out, go for it. Just have some before test data and after test data and report on the improvements or lack of improvements.

And I have a 200 mpg carburator for you also.

I always used to hear about that. I wondered where it went.

snake oil, no matter how many times you post what it does

I was just wondering ( I dont know why it posted so many time my comp messed up)

"buy a new pair of sneakers.." instead.

Do a search, 1FST2M6 dyno'd a car with one. It lost horsepower and torque.
The infomercial is a fraud. The dyno test they do is at 2 different RPM's. The "before" is at a lower RPM and the "after" is at the peak hp/rpm.

hi those things do not work..think about it the air commes in at xxxcfm's per minutes then it slams into airfilter and all that convoluted twists in the housing, then slam into spiral thingy, which is supposed to make it twist, in to throttle valve , then past restriction in plenum neck, then into flattened area, then it gets split into six different passages, then into restrictive space right at fuel injector, then into valve areas then sucked into piston and detonation and out she goes. there is no way that it can possibly keep that spiral going on all those rough surfaces going down.. thats why poeple port and polish.. i do not think they wok save your money and port polish your exhuast manifolds or other easy proven mods.......good luck

ps forgive my somewhat nontech description of air flow .. i am not engineer...
