Default Gas mileage with gen III intake

I'm planning on purchasing this system, but so far I have not do anything to my car completly stock, will installing this kit decrease/increase gas mileage or pretty much just stay the same. I do alot of highway driving and short drive to work, an I'm pretty happy with the mileage I'm getting , I plan on getting exhuast and HFCs in the future but I'm opting for intakes first.

I just wanna know what you guys/gals have experienced after installing you intakes. Gas mileage wise

So you want to get a performance mod but are concerned with mileage? That's a first.

Your gas mileage will definitely drop due to your foot becoming heavier to listen to that sound

There won't be any difference really in mpg, unless you start driving the car harder.

There is times to play around, none the less when I am not playing I do stay aware I my gas mileage, and drive moderatly slow(obey the speed limit). Let me rephrase my question.

Under regular/casual driving will there be a loss on milage.

I have had my intakes on for a while and my gas mileage has not dropped noticeably. I don't think that it will drop.

I don't have the 3g. But it will sound good. It sounded good when I switched to JWT. I have Injen now.

Even if it did, it won't be anything noticable IMO

I seem to get more or less the same milage on the highway, never paid attention to exact numbers.. but then again it's really hard to tell since there are so many factors involved, weather, altitude, in city driving, highway, car mileage etc..

Did some researching for you

If modifications cause the engine to run moderately lean, there will be a slight increase in fuel economy, sometimes at the expense of increased NOx emissions, much higher exhaust gas temperatures, and sometimes a slight increase in power that can quickly turn into misfires and a drastic loss of power, as well as potential engine damage, at ultra-lean air-to-fuel ratios

Thanks Sam. Getting a tune after doing modifications can help with mpg.

Intake + Cats + CBE = a little better mpg. Now add 4.08 gears 700 rpm more at 100km and your milage drops, 2800 vs 2100 in 7th. 4.5 mpg at least. 37 mpg to 32 mpg, but it does the 1/4 in 12.800.
Small price to pay for performance.

More horsepower takes more fuel (part of the "no free lunch" axiom)...Though the differences should be minimal under less than WOT condidtions....

In theory, gas mileage will go up a bit due to the car running a bit fat in the fuel/air mix, so you get more HP out of the deal.

But, the end result is that you will probably not notice much, if any, increase or decrease, given the same driver input.
