      Replaces Malfunctioning Oxygen Sensor. Your Jeep has multiple O2 (Lambda) sensors, which the engine management unit uses to adjust fueling so that you get the best performance and mileage, plus the lowest emissions. If one of this sensors goes bad, your engine won’t run right and you even risk damaging the cat. Fitting a quality replacement Oxygen Sensor like this one is the best way to make sure your engine and exhaust system are operating at their best.

      High Quality Materials. You can’t cut corners with quality when it comes to the Oxygen Sensor. The heat and climate where the O2 sensor lives is extremely challenging. Manufacturer uses high quality metal and plastic materials to make sure this replacement part can withstand the heat and corrosion.

      Direct Replacement for the OE Part. Fitting this Oxygen Sensor is simple and straightforward. It just replaces the existing sensor screwed into the exhaust after the catalytic converter.

      One Year’s Limited Warranty. A limited warranty for 12 months or 12,000 miles covers the Oxygen Sensor

      Application. The Oxygen Sensor is designed to fit the factory rear, post-cat position on the TJ 4.0L Jeep Wrangler from 2001 to 2003.
