## Description

Every Bosch Oxygen Sensor benefits from the technological and manufacturing experience gained from decades of production since the first Oxygen Sensor was invented in the late 1960's, ensuring long-lasting, superior performance that you can count on. Bosch Oxygen Sensors are 100% tested for full functionality to ensure every sensor meets Bosch's rigorous standards for quality and performance. 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 type connectors and harnesses, along with gaskets or crush washers as necessary for installation, 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 you money when filling up at the gas pump.

Replacement O2 sensor on engine manifold in the front of the engine. Will need a special socket, easy to find at a Auto Parts shop or anywhere you can find used tools. Easy 10 minute job.

### ⭐⭐⭐⭐⭐ Lifesaver!
*by R***R on June 23, 2012*

This sensor was for my Hyundai Elantra 2004, I had my sensor light on for several months. I finally purchased this product and took less than 10 mins to install using the sensor socket (must have) purchased on Amazon as well, reset the battery and bamm!!! check engine light off! I was able to get it smogged and finally get my tags. I would recommend this product to anyone with the faulty oxygen sensor. The price was excellent compared to other sellers. Highly recommended!!!!
