Description

The Walker Products 350-34039 is a heated narrow-band oxygen sensor designed as a standard replacement. It features a 4-wire direct-fit design for easy installation.

This oxygen sensor monitors the oxygen content in exhaust gas to determine the air-fuel ratio for improved combustion efficiency. By measuring oxygen levels, it helps fine-tune the air-fuel mixture, leading to better fuel economy and reduced emissions. It is constructed with a ceramic and metal body, incorporating gas-permeable platinum electrodes for accurate sensing and a protective coating to prevent erosion.
