## Overview

The Bosch 17321 Wideband Oxygen Sensor combines over five decades of Bosch innovation with a rugged double laser-welded stainless steel body and a fast-acting heater to deliver rapid, reliable sensor performance.

## Description

Every Bosch Oxygen Sensor benefits from the technological and manufacturing experience gained from decades of production, since first inventing the Oxygen Sensor in the late 1960's, ensuring long-lasting, superior performance that you can count on. Bosch Oxygen Sensors are 100% tested for full functionality, resulting in a seared appearance of the protection tube, to ensure every Bosch manufactured sensor meets Bosch's rigorous standards for quality and performance. Exclusive double laser-welded stainless steel body is totally submersible and sealed tight to protect against damage from exhaust emissions — ensuring a longer sensor service life. Fast-acting heater optimizes sensor operation on Planar and 3, 4, and 5 wire Thimble type sensors allowing the oxygen sensor to reach its operating temperature quicker – within seconds – for optimum performance. True Direct-fit OE connectors and harnesses, along with threads pre-coated with anti-seize compound right out of the box, make installation simple and hassle-free. It’s critical that oxygen sensors are replaced at the suggested intervals provided by vehicle manufacturers before the sensor fails. Following the recommendations will prevent long term damage to a vehicle’s engine, reduce harmful carbon dioxide (CO2) emissions and save money when refueling your vehicle.
