LOl, thats great.

This piece of crap has been covered several times before, I guess there really is a sucker born every 5 minutes.
turbonator, spiralmax, whatever you call it, its all the same $0.39 piece of metal. Does nothing for modern cars, cant and won't. PERIOD.

Sit down for a minute and trace the path of the incoming air all the way to the combustion chamber then tell me how this does a damn thing to effect fuel economy or performance. Swirling air.....lol

Sorry you wasted $149 for two of them.
