Description

The Walker Products 350-341055 is a heated oxygen sensor designed to measure combustion efficiency by analyzing the oxygen content in exhaust gas. Engineered as an Original Equipment Manufacturer (OEM) replacement, it provides essential diagnostic feedback to the ECU. This sensor can help improve fuel economy, reduce emissions, and prevent the illumination of the Malfunction Indicator Light (MIL).

Features include electrodes coated with a gas-permeable platinum layer that prevents contamination from combustion residue. This ensures accurate measurement of the air-fuel ratio for optimal engine performance and cleaner exhaust.
