I bought one of those drop in k&n filter for my 2004 lancer es and now she's eating gas like V8 can someone help me? Thanks

 

have you dissconnected the battery to reset the ecu?

also have u been driveing harder or on the highway going faster? sucks more gas if u stay on it..


try puting the stock filter back in see if it gets normal mpg

 

Uh....are you on the gas more? Did you hit the honeycomb when you installed the drop in?

 

if you hit the honeycomb thats not good at all...

 

no i didn't hit the honeycomb..... but i think i didn't disconnect the battery at all. I'll try to do that. How long should i disconnect it to reset the ecu. Thanks for the super fast reply guys!

 

disconnect it and leave it off for about 10-15 mins.......

 

i deff messed my honeycomb up when i put my intake on and i havent had any problems that im aware of for the past 2 years...

 

thanks guys i'll give it a shot

 

honeycomb? wtf are we talkin about.

 

The MAF ( or is it MAS) that measures the amount of air coming in, have you changed your intake? Look inside the black box, its a honeycomb type material.

 

you know what, i was wondering about the honeycomb. When i had my chevy s-10, i "descreened " the intake by taking out the honeycomb.It was a very common mod cause the corvette had a similar MAS and the only thing was that they didn't have a honeycomb. the only thing i noticed after was that i had better flow. and more power!
So i am wondering if anyone here does the same thing?
anyway, to answer the question, i get about 13/14 mpg, that's worse than my v6 pushrod 4.3l truck, i think you might be on the throttle a little more w/ the filter. when i changed to the hks, my SES light came on, and i had to reset it(unplug battery), so if your ses light did not come on, i don't think that you will have any real problems. you are probably losing milage by trying to see if the filter made any difference.

 

Yeah you definitely don't want to take out the honeycomb, thats sure to trip a CEL.

 

i don't remember seeing a honeycomb thingee in my black box when I did mine...maybe I just missed it?

 

you would notice it its in the bottom of the intake box basically in the tube... u probly didnt mess it up just putting the drop in filter in. unless u took out the whole box which i dont c y you would.. honestly u could of got some bad gas and could b driving different i know mine totally changes with different tanks of gas etc...

 

All GM's hotwire MAF's do have honeycomb since I have a 3.5 inch MAF from a LS1. The Z06 has one slightly bigger.

You must have seen either Nissan's hotwire MAF or Linginfelter's (sp) upgraded MAF for GM. I think Ford doesn't have a honeycomb either.

The honeycomb is there to straighten the airflow, so your sensor(s) can read it w/o turbulence at idle.
