just get a short ram and a cold air.....best of both worlds. just switch 'em when needed!

"intakes actualy improve gas milage" - I have never heard such rubish
an intake will not improve your gas milage.

warmer air (from SRI and metal piping) + more air (from crappy filter) + more gas (to compensate for air) = decreased gas milage

it decreases it but i gained my low end and gas milage back when adding my header and exhaust, but lost it again when i added my 17s lol

How in the hell do some of you guys get 300+ gas milage!??!?! I am LUCKY to get 240-250. ALL THE TIME.

 
Rep Power: 320

depends on how you drive. i average 300-330 up to the light. But i keep my rpm's on average 3k.

im lucky if i get to 300 sometimes out of no where for seemingly no reason though i get like 330 or something really high, o also i found out our cars only hold 12.2 gallons not 13.2 like advertirsed lol

I always gas up between 350 and 400 miles. If you floor it from stops a lot or drive faster than 60-70 on the highway a lot, then your mpg will suck. Don't forget that your mileage will probably be off if you have aftermarket wheels or tires.

i sitll get 300-330 miles for about 10 gallons of gas with 17's on.

yes it does improve gas mileage i used to get 320 miles per tank now i get arround 370 and i drive hard

lot's of people, including some mechanics told me that intakes improve gas mileage, but after reading all this I dunno what to think? Either way i'm still gonna get a CAI, but it's not much of a priority on my to get list...

i always gas it between 350-400, but my gas light comes up at 340 and i just hold off on the gas light till i reach like about 45 miles on gas light. then i gotta fill up before i hvae to start pushing the car to the gas station. i always full tank the car to about 12.3

well so to improve my gas mileage with my cai i would have to get header and exhaust so that the air would flow better?

 
Rep Power: 338

after you get the CAI, drive like you normally would and see for yourself...a lot of ppl get the intake, like the sound and floor it too much to get even 32MPG. (that kind of happened to me)

dunno... just put the intake it won't hurt your car..... cold air....

 
Rep Power: 294

i do drive normally and get like 26-30 mpg every now an then, but i notice that when i start to accelerate from dead stop it is pretty slow than normal. and im not trying to floor it or anything, just trying to drive as normal as i usually do(dont rev it pass 3k)

It helps more if you do all three, then tune the air/fuel mixture to 14.7:1 ideal with a vafcII or something.

 
Rep Power: 294

cuz i thought having an exhaust and headers would decrease the gas mileage on our cars. so again why would it improve our gas mileage with i/h/e?

I get 350 to 400 miles to a tank with a stock intake and I live in Houston where the humidity and temperature is high 90% of the time. Brother ran the same stock on his civic and then bought a AEM CAI and increased his mileage a bit.

Your civic is adjusting to how much fuel is going in but not so drastically to where you should have these devastating numbers. The car does manage how much air is going in but the air is denser which will give better number no matter what unless you have another problem somewhere else. In all my family, there are never been a decrease in mileage due to an aftermarket intake.

But performance wise, you might as well save your money. Not worth it.
