Air Filter question

I remember reading somewhere on this forum about a device that you can install on the air intake line that "swirls" the air coming in, and provides some improved performance, but for some reason, I can't recall any of the buzzwords in that thread to be able to find it, and get the link, so I can look at ordering one of those for my 98.

Thanks in advance!

I think it is called a Tornado Device. At one time at least, NAPA sold them. Otherwise you might have to Google them. Somehow, I think if they would do what the makers claim, the car makers would use them, as they would sell their first born to stretch their mileage claims. Let us know how it does.
Regards

thanks! I think that was the one...

I don't think I'll be trying it, though...

It's always amazed me how these companies can get away with ripping off millions from the American public with this "gas saving" garbage and how the American public falls for the garbage these companies pump out. Thanks for the link.
