New O2 Oxygen Sensor Downstream & Upstream for Saab 9-5 Volvo 960 9000 S90 V90

Automotive Oxygen Sensors An oxygen or O2 sensor is an electronic device that measures the proportions of oxygen (O2) in the exhaust gas. This sensor is a crucial component of a vehicle's engine management system as it helps the engine run more efficiently and cleanly. Product Features: ● Direct fit for Saab 9-5 Volvo 960 9000 S90 V90. ● Replace OEM #: 8644472, 9170045, 8646844, 9170365, 9175481, 9170201, 8644474. ● Fast response time to ensure optimal performance. ● 100% testing before leaving the factory. ● Built to strict quality control standards. ● Easy to install, durable, high-quality materials used. Benefits: ● Improved fuel efficiency by adjusting the air-fuel ratio, resulting in reduced emissions and better gas mileage. ● Enhanced engine performance and power by providing precise data to the engine's computer. ● Reduced harmful emissions by ensuring the engine runs efficiently and cleanly. ● Longer sensor life due to durable construction and high-quality materials. ● Easy installation and maintenance, saving time and effort. Additional Features: ● Compatible with both downstream and upstream exhaust systems. ● Check engine light (CEL) elimination by providing accurate oxygen level readings. ● Improved engine reliability and durability. How to Choose an Oxygen Sensor: When selecting an oxygen sensor, consider the following factors: ● Vehicle make, model, and year. ● Upstream or downstream sensor application. ● Sensor type (heated or unheated). ● Sensor specifications (e.g., voltage range, response time). Installation Tips: ● Use a torque wrench to tighten the sensor to the specified torque. ● Apply anti-seize compound to the threads to prevent seizing. ● Check the sensor's wire harness for damage before installation. ● Reset the engine's computer after replacing the oxygen sensor.
