I actually got about 1mpg better with every mod so 3mpg over a 10 year period I'll have paid for the mod's and they are fun having.
actually it's a lot more lol I put on about 10,000 miles a year so 10,000 / 3=3,333 X $4.00=13,000 a year I can't afford not to have mod ed it. + I save .10 cents per gallon on top of that because I use e-30 ethanol. so 7,000X.10=700.00 a year.

I'm no mathmagician, but...
Let's say you went from 11mpg to 14mpg and drive 10k miles/yr.
10000mi/11mpg = 909 gal. 909gal x $4/gal = $3636
10000mi/14mpg = 714 gal. 714gal x $4/gal = $2857
$3636-$2857 = $779/year savings in gas by increasing mileage by 3mpg
Not $13,000

Right?

ya but I like my figures better. I guess for some reason I was figureing it at 1mpg lol

What did they do that you don't agree with?
Or how would you test it differently?

I guess the fact that they did the testing on a non-N/A vehicle is one.

I think most people on here think the same.

They are full of crap did you watch it.

Yeah, I saw it. Other than choosing a different vehicle to test with (if you believe that CAI's only work on V8's) I don't really see any problem with the logic and thought behind the testing.

P.S. With the exception of Canada, Australia is probably the closest country on the planet to the US in terms of the kinds of cars being driven on the road. Lots of Ford and GM V8's.
I mention this because I'd imagine they would have tested a V8 if they thought that was a factor in CAI theory. (Just a hunch of course).

If you watch it all the way through - this is basically what they do:

1. Test with stock setup (baseline)
2. Test with Pod Filter (apparently they did a previous episode to see if filter types make any difference to hp)
3. Test with no filter (to see if a filter adds any air restriction)
4. Test with headlight removed (to simulate cold air blowing on the filter while driving)
5. Test with cover over Pod Filter (to isolate temp from engine)
6. Test with rigging the air filter right next to a cold air fan blowing right on it.

None of the tests had any hp gain...they got about a 1% gain in the last test - but clearly that isn't a practical setup!

A CAI is not the air box or the filter it is the combination of the air tube filter. The test they did is change air filters and air box that is not a CAI.
Now if they would have actually switched out the stock air box, tube,and filter that would have been a test.
