      Description

      Save Fuel Costs. If you’re wondering lately why your fuel costs have gone up, then your current oxygen sensor might have already gone bad. If you want to save on fuel costs again, equip your vehicle with this NTK Performance Rear Oxygen Sensor. This oxygen sensor accurately measures the oxygen content in your exhaust and keeps its air-fuel ratio balanced. A bad oxygen sensor can send a faulty signal to your vehicle’s ECU, causing your engine to start too early even if the air is not enough. As a result, your engine uses more fuel and decreases your gas mileage.

      High-Quality Construction. Made with NTK’s premier technical ceramics, the NTK Performance Rear Oxygen Sensor is guaranteed to be of the highest quality. This oxygen sensor also comes with a platinum-coated tip and built with waterproof connectors that are suited for long-term use.

      Easy Installation. The NTK Performance Rear Oxygen Sensor follows an easy installation as long as you’re geared with the right tools and some mechanical expertise. For

      Comes with a 60-Day Warranty. NTK oxygen sensors are covered against manufacturer defects for a period of 60 days. NGK Spark Plugs, the manufacturer, will repair or replace the product without cost if you’re able to meet their warranty policy.

      Application. The NTK Performance Rear Oxygen Sensor is made to fit 1999-2006 5.3L Chevrolet Silverado 1500 models.
