Re: Kn cold air intake
I'd just wait until the car tells ya. If you're into towing, off roading, etc I'd probably change it sooner. So prior to the install of the k&n my average mpg around town was always around 16.8. No heavy foot just the same driving around town. After the install 100 miles later the same driving around town it reads 18.9 mpg. Idk what to believe but it's what I'm seeing on my dash. Regardless it does sound pretty sweet!!
