Do Cold Air Intakes really give you better gas mileage?

Increased horsepower is great but I want to know if a Cold Air Intake will actually give you better gas mileage. I bought a tonneau cover for my Toyota hoping to get better gas mileage like claimed on the website, but no change in gas mileage. Maybe it's because of my lift, I'm not sure. Answers please.

Anything that decreases pumping losses will, in theory, provide you with better gas mileage.

Usually it wont, the reason being is when the truck sees colder air it adds more fuel in open loop operation.

That's why the K&N CAI is getting removed from my S/C'd S when I get her back... deck plate mod anyone?

I would venture to think that cold air into any boosted application is a plus, should reduce detonation as long as the AFRs are correct.
I think that people that have issues with intakes and SCs are having AFR problems (not enough fuel)

Short answer: No.

And, most bolt on ones are severely overpriced. You can build your own for what, under 100 bucks? Someone had a thread on here about this.

Re: Do Cold Air Intakes really give you better gas mileage?

With my deckplate, my scanguage II claims about 1/2 a mile per gallon increase, and doing the math after fillup seems to keep showing a slight increase. Not much though. I'm usually pretty conservative about my driving, and it's about the same routine week to week. I like to keep track of it as much as possible.

just pump more air into your tires - even with abnormal wear your $ saved should be greater then money you will spend on new tires

or just dont drive it

K.I.S.S. - keep it simple, stupid

Re: Do Cold Air Intakes really give you better gas mileage?

Both yes and no. If you flow more air for more power it's more fuel. But the colder air means better fuel mileage if you CAN stay out of it. On a freeway trip on cruise control you'll see better mileage. But like they said you can make your own for cheap. Mine was under $30 for everything and with the maf got me 2-3 mpg better avg. But when on it got me 4-5 worse. Horsepower costs you. Money and more importantly gas. But there are what I call free mods and those are the effeciency things like better flow and proper air in tires. Some
are just mileage but some are more hp and better mileage. On my old Dakota I went from 9mpg to 18-24 depending on how much freeway. Headers intake tune exhaust and ingnition. And lowering = less air resistance. That got me from 22-24 in the end. Good luck and keeps us posted.
