I had replaced my stock filter with an aftermarket one and my gas mileage has gone down bad. I really didn't think I had such a heavy foot. Has anyone encountered this before?

 

what filter are u using? a named brand one like k&n or some aftermarket one? and this is a drop in filter we're talking about, or an actual filter that replaces the stock air box?

 

next time you post, lay off the "..........." thnks

 

It was a SARD filter that replaced the stock box. Was there something wrong with the dots? It only implied that it was a question. I won't use the dots again.

 

haha try getting 220 on a full tank

 

I've been getting 25, but thats an NA EJ22 lightly modded.

 

i get about 250 to 300 miles on a tank of gas


wrx

 

250 repeatedly on an 04 with 2200 miles.

 

Eluminex is that mostly highway miles you're putting on to get 330+?



:banana:

 

Its not a good idea to run your car til the light comes on, but that is still more miles than i can get. Someone suggested reseting my ecu. How do you do that for this car?

 

There are several ways to do it. One that I use is to disconnect the neg terminal of your batt, then depress the brake pedal for 5 or 10 secs. This will fully discharge the system. Then wait about 10 or 20 minutes, reconnect the neg term and your done.
