Do these do anything to save you money? Has anyone you know claimed these will save gas? Just recently completed a 3 week 1000 mile test. Actually a 3000 mile test, 1000 before the fuel saver, 1000 during, then 1000 after. ZERO difference. This is not the first time I've heard these findings.

I'm glad I didn't have to buy the one I used, it was given to me to try out. You gotta wonder why these won't be found on the shelves at your local auto parts store.

I am curious to hear from anyone as to the amount they save or what increase in mileage they experienced.

If it's the product I think it is, all it does is separate people from their money. There is no way that device can help fuel economy.

If you want to get better gas mileage, make sure your tires are properly inflated, slow down and take all the extra weight out of your car. Those are all things proven to improve gas mileage.

I was skeptical also. But I bought one anyway at JC Whitney because they have a 30 day return policy and I have had good dealings with them on many purchases.

In my 1997 Lexus LS 400, I experienced an increase in highway fuel mileage of about 15%. However, results are mixed with the in-town efficiency.

I am still trying it out and reporting my results regularly. You can see my full review at http://www.customrides.com/tornado-fuel-saver-review/.

It is definitely worth a try if you buy it from a reputable source with a good return policy.

I read your article and when I got towards the end and read the part where you "replaced" the air filter, I think that was all you needed to do. I seriously doubt it was the $60 cookie cutter.

Something else came to mind before I even tried this device. I was more concerned one of those cheap metal fins would come off and get sucked into my intake and chewed to pieces by a valve. Secondly this swirling action seams restrictive rather than more efficient. Think of it, take a straight line then make a swirl shape out of it. Looks like the air is running around in circles taking longer getting into the combustion chambers?

The bottom line on something like this is that it would be installed in every car if it increased gas mileage even as much as two percent. If it works, why isn't it standard in every car? Car companies would kill to have something that gave them a gas mileage edge on the competition, so why is no manufacturer using this product or something like it? There's no conspiracy here -- the product isn't being used because it is useless.

Putting in a new air filter can certainly improve gas mileage. The dirtier the old filter is, the more impressive the new filter will be. It can really help performance, too.
