NO it's not twisted "bollywood" version of the Terminator, it's an intake gadget. A guy at the gym, who is an F-150 owner and discussion board regular told me about it and I did a search and found this. Anyone ever heard anything about these? HE says on the discussion board he goes on that the guys who have bought them have said they've run into good results.
Have a look:

Yep, try a search here.

This topic gets brought up every few months.

 

The usual conclusion: if it sounds to be good to be true, ....

 

Put it right next to the Tornado. In the trash

 

What blows me away is that when people try to sell products like that they come up with the most incredible names.
Tornado, The Turbonator, it sounds unrealistic to begin with.
Judging by the extra dampener etc. on the 4Runner's intake hose, I think Toyota put enough research into air intake patterns.
If a cheap piece of metal would increase the fuel mileage, I am sure Toyota would have put that in to begin with.

 

There's a lot of gullible people out there that want to believe in crap like this and swear they can tell it works by the seat of their pants but when tested on a dyno the results are negligible.
