The great intake debate!

But you don't need a CAI for that, just press the gas pedal harder and you'll get more air into the engine So what's the difference in the end?

Your getting more warm air into the engine with the stock box, you are getting more cold air with a cai, cold air is denser than warm air.

And how does that make the exhaust gas more polluting? You still haven't explained that!

More air means more exhaust. Duh, of course!!! So does more driving. I still don't see the point.

If, say, 20% of the exhaust are emissions, if you put more air in, you'll get more exhaust, but still, only 20% of that will be emissions. So how is that worse?

Smog measures the percentage of pollutants in the exhaust gas and so far nobody has shown that more air in the engine increases the percentage of pollutants. You've only said that more air in equals more exhaust, to which I say: DUH!

You are saying it yourself, that the air intake can affect emissions. What more can I say.

20% of 100 is the same as 20% of 1,000,000 in "relative" terms. THE SAME. That's how smog is measured in percentage!!!

Yes, I am putting out more exhaust, but it doesn't have a higher percentage of pollutants, it's the same percentage!

A CAI is causing more emissions the same way driving more causes more emissions. Someone driving 100 miles will cause double the pollution of someone driving 50 miles. Simple enough for you? According to your logic the first guy should not pass the smog

To say that 20 percent of 100 is the same as 20 percent of a million is silly, 20 pph is different than 20 ppm. You will not pass if you are putting out 20 pph but you may pass with 20 ppm. I don't live in California and cannot tell you how they do smog test. What is the baseline and what percentage do you need to pass? To say that burning more fuel does not equate to more emissions or noxious gas is silly.

HA HA enough to know that burning more fuel makes more emissions.

Other than increased pollution , none .

Excuse me , I got this dumb ass deer in my yard . I got to eliminate him from the gene pool . Besides...... I'm hungry ........ Can you say "Smoked Tenderloin" . See Ya after dinner .................

I see a lot of increased pollution too: the gun powder used to eliminate the deer, unless you're using a bow and arrow and then there is the smoked tenderloin, which speaks pollution with a capital P

Some pictures would be nice

20 % of 3.0 liters (.6) ( or whatever they measure air in ) is greater than 20 % of 1.5 liters (.3) . I'm not sure ( We don't have smog test here in South Carolina ) , but I would guess that the percentage would based in part by the number of cylinders . I mean that is the whole idea behind CAFE , which starts next year ...I think . A 4 and 8 cylinder may have the same percentage , but the actual number value won't be the same .
