CFM+ (CFM PLUS) Air Intake Heater Delete Plug

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 (see picture below) and creates significant turbulence in the airflow going into your engine.  By removing this heater, and replacing it with the intake-heater delete plug, you eliminate the restriction in your airflow and eradicate the turbulence created by this relatively unnecessary part.

An additional feature of the intake-heater delete plug is that it is drilled and tapped with a 1/8” NPT port which allows you to connect your boost gauge exactly where you need it, at the intake manifold.  To install a boost gauge, simply remove the 1/8” plug (not shown) from the center of the intake heater delete plug, and insert the boost gauge fitting.
