CNC Fabrication™ L99-03 7.3L Air Intake Heater Plug
MODEL/YEAR(S): 1999-2003
ENGINE SIZE: 7.3L
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 the heater, and replacing it with this plug, you eliminate the restriction in your airflow and eradicate the turbulence created by this relatively unnecessary part.
FEATURES:
- Drilled and tapped 1/8” NPT port for a pressure sensor
- Fits both stock air intake manifold as well as CFM Plus 7.3L intake system
- Made in house on our CNC Lathe turning center
- Metal gasket with infused rubber o-ring for a clean install
