High-Precision MAF Sensor for Optimal Engine Performance
Engineered with advanced thermistor technology and a durable anodized aluminum housing for superior heat resistance and longevity. The platinum-coated sensing wire ensures ultra-accurate air flow measurement, directly improving fuel efficiency and throttle response.
Perfect Fit & Plug-and-Play Installation
Direct OEM replacement (55505735/AFH70M-129) for Cadillac XT4 (2019-2021), XT5, and GMC Acadia (2020-2022) with 2.0L engines. Precision-molded connectors and factory-calibrated signals eliminate the need for reprogramming.
Built for Extreme Conditions
Multi-layer hydrophobic filter prevents dust/water intrusion, ideal for off-road or harsh climates. Laser-welded seams and military-grade circuit boards guarantee reliability under high vibration.
Emission Compliance & Cost Savings
Restores factory-level air-fuel ratios, reducing hydrocarbon emissions by up to 18%. Bulk pricing available for fleet owners and repair shops—stock up on the most failure-prone sensor in turbocharged engines.
Tested Beyond OEM Standards
100% bench-tested for voltage consistency (0-5V output range) and subjected to 500+ thermal shock cycles. Includes anti-static shipping packaging to prevent calibration drift.
