I figure $15, just give it a try. It's a Tornado clone. I installed it to my car yesterday. Took me 5 mins. Not sure if it gives better mileage yet. Car seems to go a little faster.

I have been a helicopter mech. for 28 yrs . In theory its junk , but some corvette intake manifolds have the same thing from the factory . Who knows may be a few % gain on nasty carburated engines .

Take it back off. There will be additional differential pressure in your air flow across it.

This concept is another form of snake oil. It violates the conservation of energy law. You cannot get more energy out of a system than you put in. You will always have less due to losses. Think about what causes the supposed swirling low pressure at the exhaust. All you are doing is adding a restriction to your exhaust system.

The Corvette story is a little different. As i understand it, the reason for the vanes on the intake side is to promote better mixing of the air and gasoline prior to combustion for smog reasons, so the restriction serves a purpose and no conservation laws are violated.
