    Top Street Performance 81029 Airflow Sensor Wiring Harness Features:

    • This 1-piece wire adapter harness is designed for converting the smaller 78 mm LS1 3-wire mass airflow (MAF) sensor to the larger 5-wire LS3 car-style MAF with an integrated intake air temperature (IAT) sensor
    • Built using factory-style connectors, seals, and high-quality terminals to ensure a secure, reliable connection with your LS3 MAF sensor
    • This plug-and-play adapter harness eliminates the need for cutting or splicing wires, allowing for a quick and clean installation when upgrading to an LS3 MAF sensor
    • Designed with standard aftermarket wire color coding, making identification and connection easier during installation
    • Ideal for performance builds, engine swaps, or upgrades requiring the larger LS3 MAF sensor for improved airflow and accurate air/fuel ratios
    • Converting to the LS3 MAF sensor requires proper ECU tuning and rescaling of MAF tables to ensure optimal engine performance and accurate air/fuel mixture
