Have a 01 250 Super Duty 7.3 Why do these have an air intake heater if they run better with cold air this is my 1st diesel and am trying to get better economy drive 500 miles a day everyday love this truck, has 378000 and all i have had to do is put a trans in it
Removing the AIH coil will not affect cold start up in any conditions.*The PCM only commands the AIH to activate to reduce white smoke during extended long idle periods at low ambient temperatures. Specific conditions must be present before the heater is activated per Ford:
Ambient temperature must be below 32°F
Engine oil temperature (EOT) must be below 131°F
Vehicle power must*remain between 11.5 and 15.0 volts
Parking brake must be applied
The transmission must be in Park or Neutral
Glow plugs must be off
Most people on here end up removing the AIH (intake heater) and using that port to install their boost line for their gauge. It is not necessary especially in the climate that we live in. It blocks air flow and might (not proven) help performance and MPG but is probably negligible.
