I just purchased an K an N cold air intake, and i was wondering would i have to change any of the A/F ratio? one of my friends brought up this question and i havent been able to find out the answer. thanks for your help !!

 

you mean like tune it? i wouldnt think so, that is what the intake air temp sensor is there for, it'll auto matically adjust for you by sensing cold air coming in then turning on the injectors just a little more then usual, so cai=crappy mpg

 

Thanks
