Should I expect better gas mileage by replacing this?
 

So yesterday you all saw my filthy cabin filter...well today I replaced my stock air filter and intake tube with a K&N and a Z-tube. I don't think the previous owner changed it once. My car only has 35K miles.

Tell me it shouldn't be that black.

It shouldn't be that black...

smoker maybe?

Damn thats insane. Makes you wonder how often they changed their oil.

you will see slightly better gas milage maybe 1-2 mpg only if you get a tune...

i should get a tune? How come? Shouldn't I get better gas mileage with a clean air filter?

thats the air filter... sucking in air from the outside.....

oops, wrong thread...

that filter is filthy.

You should get better mileage but this is in the wrong part of the forum.

i didnt get better gas mileage... i have z-tube with amsoil drop in filter... just try resetting your ECU...



+1 with this thread being in the wrong section of the forum

i thought it was in cleaning...since I cleaned my air filter lol but you're right.

Wow yeah that's pretty dirty. How often do you inspect it?

Wow, mine is still all red and I think mine is filthy lol.

You will see better MPG.. You don't need a get a tune over a z tube.

I haven't even owned the car for 2500 miles so this is my first time inspecting it.
