- FIT 2017-2021 Chevrolet Colorado, 2018-2021 Traverse, 2019-2021 Blazer; FIT 2017-2021 GMC Canyon, Acadia; FIT 2018-2021 Buick Enclave; FIT 2017-2021 Cadillac XT5, XT6. Specifically for 3.6L V6 engine platforms.
- This comprehensive sensor kit integrates 2x Upstream (Sensor 1) and 2x Downstream (Sensor 2) units. The hardware features a dual-layer stainless steel housing and precision-fired ceramic elements to maintain a closed-loop signal feedback system within the exhaust geometry.
- The sensors are engineered for thermal shock endurance, addressing erratic voltage feedback and air-fuel ratio signal lag in the engine monitoring loop. This hardware restores factory-specified signal characteristics and maintains proper engine-to-chassis geometry for secondary air injection monitoring.
- Each unit undergoes cycles tested validation to ensure consistent heater resistance and response time. The hardware integrates an OE-matching 4-wire sealed connector to prevent moisture intrusion, meeting OE specifications for acoustic decibel limits and signal integrity across high-temperature exhaust cycles.
- Professional installation is required; use an O2 sensor socket to ensure proper torque and avoid thread damage. Verify your vehicle's harness length and plug configuration before hardware integration. Replaces Part# 250-241212, 12662391, 12671382. Specifically for 3.6L V6 Naturally Aspirated systems.
