  1. Installed K & N Intake, immediately threw off check engine light...help!

    Performance Mods - Engine - 4.7 Liter V8
    I installed a K & N intake today and right away the check engine light came on. Pulled the code and said IAT sensor high load. What could be causing this? I've double checked that the sensor is plugged in, and had no problems at all before the installation. Truck is a 2008 4.7L flex fuel engine...
