After installing Injen intake... I noticed that instead gettin 19mpg im gettin 14mpg. WTF? Did i did something wrong?

 

I noticed my mileage dropped when I put in my Y-pipe. wtf too?

 

youre racing around more now because you like the sound...

 

i thought so, but im not sure
needs more research

 

when you put in an exhaust or intake you effect the in/out pressures. The car was setup to have certain back pressure for "optimum" fuel economy. An intake should not effect MPG too much. It actually should go up b/c the car has to do less work to get the air in. However an exhaust will effect the MPG b/c of back pressure changing. Hope this helps. You may want to reset the ECM by removing the negative battery lead and keeping it off for five minutes. Your car needs to "learn" the new intake settings.

 

Have you guys tried what MSOEMAX mentioned...if so have you noticed a change in your fuel consumption? I am looking into getting an intake and an exhaust with the impression that it would improve my fuel economy not reduce it.

 

The mileage won't go up that much. More so on the highway than in the city. It shouldn't go down too much under normal driving conditions. However you may do a lot more hard acceleration with the new intake and so you won't see gains in MPG.

 

u guys got 19 before u installed the intakes? damn, i didnt do anything and im getting 16mpg max.

 

Geez, what do you guys do with your cars?! I get 23 around town and usually 28 on a long highway trip. I have the Frankencar intake, no exhaust yet.

 

Chrisaust,
What spoiler is that? Got any more pics?

 

Heavy footed and the ECU is learning the new fuel consumption.

 

you can find them on ebay painted. here is a shot of a silver one..

Thanks!
That's perfect. I wanted a spoiler larger than the OEM lip, but not too big or one of the aluminum wings. That's exactly what I need.
