I have seen that commercial for the Tornado Air System that is supposed to turn your air filter into this amazing gas saving and horsepower boosting animal! Has anyone installed one of these on their own trucks? If so have you noticed a change in anything such as gas mileage or horsepower increase. I was thinking about one for my 1999 F150 XL 4.2 or do you think I should go with the Intake systems. I want to increase my acceleration and gas mileage. Let me know! Every one be safe and have a great day!- Andrew

 

You can do a search on this product as it has been discussed before. I did a search and from what I see, it looks like crap.

 

I've tried it on my truck and there wasn't a difference in power but a small difference in mpg, about 5-10 mpg's. I suggest getting a poweraid throttle body spacer which does the samething that tornado system does, but more..
