"Tornado Air System" (As Seen on TV)? It's "designed to enhance fuel economy and increase power. Increases gas mileage up to 24%." I just saw it in a Pep Boys ad and was wondering if it does what it says. Does anyone have it or knows of it?

Yeah, I noticed some people already spoke of this a while ago but does anyone have any new insight? Thanks.

You can have something like this machined that will work alot better.. basically get a throttle body gasket from a local autoparts store for the motor type you have and take that gasket to a machine shop and have them make a spaceer to go between your throttle body and your intake manifold that is between 1.5-2 inches and have them swirl the inside of it. this will give the airflow a sprial to it right before the runners in the intake manifold and will not impeed airflow - this is a trick done on alot of cars and is pretty inexpensive to do with fairly good gains 5-7HP.. places like summit and other part places sell premades of these for alot of cars


Sorry to be a bltch, but as someone that spends at least one day a month at the dyno for something....there is no way. 5-7hp? No way. You're missing the entire point of a plenum....it negates any flow characteristics caused upstream of it. You MAY see some kind of gain by having a 'swirl' pattern machined into the surfaces of the intake runners, but anything before that will not make any difference.
