- Confirm your old sensor’s part number matches one of the listed numbers (234-5174, 234-5713, 234-8017, 234-4961).
- Compare product photos to your stock sensor—they must look identical (e.g., connector shape, wire length, body design) to ensure a proper fit.
- Installation Guidance: While designed for plug-and-play use, professional installation is recommended if you’re unfamiliar with O2 sensor wiring or torque requirements (incorrect installation may damage the sensor or your vehicle’s ECU).
