... A decrease in gas mileage? Just curious cuz I haven't cleaned out mine for a long time =T ? (altho I searched out a thread that said you change every 100K)

TIA

 

100k? i bought mine in march and cleaned it in july, probably will buy a new one when it gets dirty again, as far as gas milage goes i have no clue

 

i would think so.... i clean my popcharger every time i get an oil change with the K&N recharger set.

 

a clean air filter is always better...but yea seriously clean your air filter and ill bet you should have better mileage, since theres less dirt in your filter and more air can get into your engine....before i had the G, i usally changed my air filter on my cars every 6 to 12 months. thats before i bought the million mile K&N then i just use the cleaner ever 6 to 12 months still....
