Anyone tried these Tornado fuel saver (or similar) devices? They claim to improve FE by 1-2 mpg, but I'm skeptic of how effective this would actually be.

 

Considering the cost, even if the product does what it says, it would take an awful lot of driving to save enough fuel with an increase of 1-2 mpg. But, if you're altruistic and just want to get the better mileage, it's a thought.

 

If improving a couple of MPG was as easy as fitting a little piece of tin to the intake, all manufacturers would do it! These things are a total waste of money. Don't bother!

 

A complete waste of money. If increasing fuel economy was that simple, at the very least every hybrid would have their own version fitted.

These gadgets have been tested before...many times, and they don't work. The logic does but the physics doesn't.

 

garbage, snake oil, scam, call it what you will. any blockage of the intake tract (outside of supercharger or turbo) will hurt performance / mileage if anything.

 

I second what everyone else has said thus far.

These FE add-ons, gizmos, tricks and so on (tornado included) all amount the blatant scams. Even if the principles appear sound, up until now they have all failed to deliver results as reported by every qualified and autoritative technical review body.

Please avoid these.

You are wise to be skeptical.
They don't work.
If they did, a better more integrated method would already be incorporated in our cars.
Or at the very least, at those world-record MPG championships - you'd see these installed.
I'd bet your money ($55 and free shipping) that they don't work.

 

Yes, we also tested the tornado and found no increase in FE.

 

Just go w/ a K&N instead and save your money with filter replacements.

I would advise against installing K&N filters particularly if the main goal is to improve Fuel economy on our hybrid vehicles.

Although with great promise and popular with the rice/tuner performance market, these filters are too porous and are known to allow large airborne particles to still pass through. This often causes concern with the increased potential for engine damage.

Also, there is the issue of the filter oil that may interfere with (or even clog) the downstream sensors. Not a pretty thought and certain to cause issues with any warranty fulfillments you may require.

Anyway, this issue has been beaten to death in this and other Hybrid specific forums. The verdict is that those who still tried it report no significant improments in FE thus making this mod a particularly bad choice. Instead, use the OEM filter replacements regularly and judiciously as Honda and Toyota (for Prius owners) intended.
