Has anybody tried the Vortex or Tornado? Its suppose to spin the air into your engine to promote better fuel combustion. I am thinking of trying one. But im not really sold on if they work or not.

If our talking about the throttle-body spacers, they do work and give quicker throttle response and performance. Average gain would be 4-9HP/and 12-14fp of torque and in most cases improve your fuel mileage. Here is also a link to TB spacers for your application.

I have no experience with this product.
Anyone else?
