Premium Narrow-band Oxygen Sensor (15717) by Bosch®. Position: Upstream. A worn-out oxygen sensor can cause engine performance problems and shorten the life of the catalytic converter. Tune-up your vehicle with an Oxygen Sensor from Bosch that is equally efficient in improving fuel efficiency and reducing harmful exhaust emissions.
An oxygen sensor detects the amount of oxygen in vehicle's exhaust gases and sends a signal to the engine computer. This signal is used by the engine ECU to fine-tune the air/fuel mixture to the optimal level to ensure maximum catalyst efficiency and a long service life. A worn-out oxygen sensor can cause serious problems like excessive fuel consumption and elevated exhaust emissions as well as shorten the life of a catalytic converter and affect engine performance. Bosch oxygen sensors are the number one choice for many car makers worldwide. Each oxygen sensor by Bosch is subjected to a 1,000 degree Celsius functional test and a leak test to ensure environmental and functional robustness. Bosch oxygen sensors feature a revolutionary Bosch patented universal connection system that is fully submersible in water and protects against contamination as well as withstands extreme temperatures and engine vibration.

Good Deal On Bosch 02 Sensors
Bosch® 15717 - Premium Oxygen Sensor
I shopped on the Internet and by phone for an hour and CARiD by far were the cheapest around for these sensors. I would have paid double for these at my local auto parts store.
