Some people thought it was a joke,
but in the past here on Dodgeforum
I have offered to put up $30,000 in the hands of a third party
against anyone who would also put up $30,000 cash with a 3rd party
as a bet that a CAI would not change MPG
in a careful test run by a third party.
I was serious and would still do this.
The IRS would not consider this a 'gamble' but a game of skill.
The best test for MPG that anyone has devised so far
is the SAE/TMC Type IV test
that can measure down to a 2% difference.
The $30,000 bet would be that tests of two vehicles
would show less than a 2% difference
when a CAI was first fitted to one vehicle
then a 2nd identical test run when the CAI was swapped to the other vehicle.
Good companies are now using the SAE/TMC mpg test to 'prove' that their product works:

The right way to do it
Goodyear goes by the book with Fuel Max test
When Goodyear introduced its new Unisteel tires with Fuel Max technology last year, and claimed that they were more fuel-efficient than its older designs, the company invited the press to come to its San Angelo Proving Grounds in Texas and observe an SAE/TMC Type II fuel consumption test, pitting old against new.
In this case, two identical tractor-trailers — a control rig and a test rig with the same powertrain, mileage, horsepower, GCW, tires, pressure, etc. — were fitted with removable, portable fuel tanks, which were weighed before and after identical runs of at least 28 miles at the exact same highway speed. Fuel consumption was measured by tank weight, and the two rigs were compared as a baseline. Three runs, which must produce results within 2 percent of each other, were made. In this case, the two rigs’ fuel consumption figures were consistently within 1 percent of each other.
Next, the test was repeated, with the control rig unchanged, and the test truck fitted with the component to be tested — in this case, the new tires. Over the course of three runs, with results within 2 percent of each other, the test truck had consumed about 7.5 percent less fuel per run.
Claim made, point proved, case closed.

Lubrizol, the maker of Chrysler ATF+4 does similar tests:

and Walmart would not buy these aero devices for its fleet of trucks until a SAE/TMC mpg test was completed:

So if you believe that CAI's improve MPG
why don't collect this 'easy' $30,000 ?
But to keep down hard feelings
ya ought to try the test in advance a few times
to make sure you are not throwing your money away
because some might say I am
'trolling for suckers'
too.
Why don't you see KN, Airaid, Volant, etc
have in their ads that they have done a SAE/TMC Type IV test
and proved that their product improves mpg
like Goodyear did?
