Keep your engine running on an accurate air-fuel signal with the MotoRad 3MF103 Mass Air Flow Sensor. Designed to meet or exceed OEM specifications, this sensor measures the air entering your engine and relays that data to the ECU so combustion stays optimized. MotoRad engineers each MAF sensor to resist contamination and stand up to the vibration of daily driving, helping it perform reliably over the long haul. Inside, a platinum-infused hot wire sensor resists corrosion for stable, consistent readings, while double wire bonding is upgraded to guard against vibration-related failures. Proprietary NTC technology is matched to OE resistance values, sending a precise signal to your ECU for the correct fuel-to-air mixture. Manufactured at an IATF16949-certified facility and backed by a limited lifetime warranty, the 3MF103 is a dependable replacement for a wide range of Isuzu, Cadillac, Chevrolet, GMC, and Oldsmobile applications from 1999-2003.

Features

  • Platinum-infused hot wire sensor resists corrosion for stable, consistent airflow readings over time.
  • Upgraded double wire bonding helps protect internal connections against vibration-related failure.
  • Proprietary NTC technology matches OE resistance for a precise ECU signal and correct fuel mixture.
  • Manufactured to meet or exceed OEM specifications at IATF16949-certified facilities for consistent quality.
  • Backed by a limited lifetime warranty for long-term ownership confidence.
