Does engine mods lower MPG?

What engine mods are gonna lower the celi's fuel mpg...? I want to put a CAI and exhaust.. is this going to lower my mpg drastically? Cause part of the reason i got my celi was fuel economy.. I traded a Toy Tundra, which i got only 16mpg on it.. and I work kinda far tongue post up some numbers if you can. Thanks ahead of time. spineyes

I could be wrong but i dont believe that minor upgrades like i/e will drastically lower your MPG. i have both on my civic and i still get 20+ mpg. dont know any specific numbers but id say go ahead and get the mods thumbsup

CAI and exhaust should INCREASE your mileage, as long as you don't change your driving habits. Makes the motor more efficient.

they increase mpg because it takes away some engine restriction as long as your driving normally but if you pushin it, it will waste more gas because ur gettin more performance out of it

Ill be the first to say they'll go down. Once you hear the Intake and the exhaust for the first time ur gonna wanna keep the RPMs up all the time, trust me, you'll wanna hear it from the time you start it till you turn it off grin

If you are modifying your car you shouldn't be worrying about that, it well go down but it's minor. Turboing the car will make it drop but it's minimall compared to the performance boost.
IMO mpg shouldn't even be an issue if you like to drive your car.

The only mod that will lower MPG is removing the butterfly valve from your air Intake box. Don't ask me why this happens. idunnoIt has to do with constricting airflow.

It you put VTEC stickers or other crap vinyl decals and stuff on your car, you will lower MPG...and respect from non-ricers. rofl thumbsdown

I've been getting about 34 highway; I'm probably pretty easy on it.

300,000 KM/Sec. Its not just a good idea, its the law.

If you do enough mods to actually increase your horsepower, your gas mileage will be reduced accordingly.

I've removed my butterfly and haven't noticed any change in my MPG.

As for what you get with other mods...why doesn't someone post up their average MPG with and without a CAI? We can debate back and forth forever on whether it will increase engine efficiency or require more gas, but there's only one sure way to know. thumbsup
