The Speed Engineering MAF/IAT breakout extension harness lets the intake air temperature (IAT) sensor be moved away from the MAF. Relocating the IAT helps prevent heat soak so the sensor reads cooler, more accurate intake temperatures. The 24" harness plugs into the factory harness. Speed Engineering notes it is commonly used on 2005–2006 Pontiac GTO and C5 Corvette applications, and that it can work as an IAT extension on 1999–2006 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks.
Features:
- Factory Harness Plug-In
- Relocates IAT Sensor: Away from the MAF to reduce heat soak
- 24" Length
- Common Applications: 2005–2006 GTO and C5 Corvette
- IAT Extension Use: 1999–2006 Chevrolet Silverado 1500 and GMC Sierra 1500
