99.5-03 7.3L Ford Powerstroke CNC Fab AIH Plug

Fits: 1999.5-2003 7.3L Ford Powerstroke

The air intake heater, which is found in ’99.5 and up 7.3 Powerstrokes, blocks close to 20% of the air path in the intake manifold and creates significant turbulence in the airflow going into your engine.  By removing this heater, and replacing it with the intake-heater plug, you eliminate the restriction in your airflow and eradicate the turbulence created by this relatively unnecessary part.


  • Drilled and tapped with a 1/8” NPT 
  • Fits both stock air intake manifold as well as CFM Plus 7.3L  intake system
  • Made in house on our CNC milling center
  • Metal gasket with infused rubber o-ring for a clean install
