Description
GEN 3 & Gen 4 LS Intake Mass Air Flow Adaptor Harness
This Top Street Performance mass air flow sensor is exactly what you need to get your LS conversion on the road.
3-Wire to 5-Wire Conversion:
- The adapter harness is designed to connect the three wires from the LS1 MAF sensor to the five pins on the LS3 MAF sensor.
- It reroutes signals to accommodate the additional IAT sensor wiring
Integrated IAT (Intake Air Temperature) Sensor Plug:
- Since the LS1s IAT sensor is separate, the adapter typically includes a provision to connect to the existing IAT wiring or integrates it into the new harness.
Plug-and-Play Design:
- Adapters are pre-wired and designed to plug directly into the existing LS1 harness and the LS3 MAF sensor, requiring no splicing or additional modification.
This mass air flow adaptor works great with our cold air intake AIR-223
