Sa NOx naman, magi-introduce ng exhaust gasses yung Exhaust Gas Recirculation (EGR) valve, ecu controlled din ito para bumaba yung temperature ng combustion. F-150 is ULEV, ultra-low emission vehicle pero "gas-guzzler" dahil hindi pwede i-compromise yung emission standards. D bale malakas sa gas huwag lang mag-pollute ng hangin.
