Put the Fleece FPE-LB7-IAH-DELETE Intake Air Heater Delete Plug in your 2001-2004 GM 6.6L Duramax LB7 and 1999.5-2003 Ford 7.3L Powerstroke to increase air flow and eliminate the intake air heater. Each plug is drilled and tapped with an 1/8" NPT port so you can install a boost gauge, nitrous, or water methanol injection.
- Increased Intake Air Flow
- CNC Machined Billet Aluminum
- Pre-Drilled & Tapped 1/8" NPT Port
7.3L Powerstroke: The air heater on the 1999.5-2003 Ford 7.3 only runs during idle in cold temperatures. The power wire comes off the glow plug relay just in front of it and, the ground goes to a bolt in the engine valley. These components are simple to remove.
6.6L Duramax LB7: Aftermarket tuning is required to turn off the intake heater.
