I have read some pros and cons on the air filter replacement. Some say the k&n will damage your sensors, while others say it was a huge mileage advantage. I live in chicago , so alot of city driving and am getting around 12mpg right now. I would like to improve that alittle . What is the final consenses on this? DiscoMike?? Maybe there is other things I can do to improve the mileage, the truck is still under warranty with 28,000 miles on it. Thanks

 

Don't do it.
MAFs cost more than gas.
