Do those "increase gas milage" devices really work ???

ROFLOL!!! Same old scam.... Piece of junk.

Also, looking at their 'Test Results' with a fine toothed comb,

Carolla: Not tested on the same machine twice. 4-years later, with cleaner gasoline going into it, it's testing cleaner... imagine that???

Same situation for the Renault Encore.... Two different tests, two weeks apart, on two different machines, performed by two different technicians. Barely an analytical method, hardly scientifically proven by any stretch!

For the Cougar, sure, maybe I'm a skeptic.... it's definately a little closer to a 'Back-to-Back' comparison than the other two. However, I'm not seeing a significant change to be able to attribute it to the Vortex Valve. Run those same two tests over again after letting it sit for 20 minutes, then starting it up and letting it run like they did, and I suspect you'll see a wide variation in the readings.

Again, the Shovie pickup, tested a year apart, different weather conditions, different gas, and the numbers came out ever-so-slightly better. Fart in the garage and you'll see a change about as great.

Look up the patent number... the description deliberately obtuse enough that nobody could possibly discern what it is, or how it works, but it sounds impressive. Dazzled with brilliance and baffled with bullchips!

I was wondering, some people say it does make a difference to them when we all know its just another chunk of crap to block the intake, but after reading the link brooklyn left in the mafs thread, i was wondering if perhaps on some vehicles with mass air sensors, that the only reason that this may of helped a bit is because it blocks off some of the feedback the mafs gets from the intake?

Just grasping at straws here for some form of possible reasoning of why anyone would see an improvement.

i am sure it helps with some and not for others.. just like getting 30mpg some of that will work with one and not the other..
