Cool Air or Tune
I have a 05 FX 4 that i am thinking of adding a Cool Air intake. But I am also considering a Hypertech or supperchips tuner. Which would give the most MPG improvement for the money? I understand that both would be the way to go, but I want to start with the best option first.
The 5.4 has a flowmaster exhaust and a K & N filter at present.
Any info on this would be helpful.
Thanks.
