AIH Delete Plug - Ford 7.3L 99.5-03

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

    RiffRaff plug looks much better in the intake than the heat coil. Move more air too.

    I make a lot of aluminum parts so I really appreciate good machining. What can I say, fit just like it is supposed to.

    Great Looking Product

    Posted by Larry on May 30th 2017

    Less than 10 minutes to install, and it really looks nice. It helps to clean up the engine compartment by eliminating unnecessary wires. And, getting obstacles out of the way of air flow is always good, too!
