They measure exhaust oxygen content and send voltage signals to the engine control module so your vehicle can maintain efficient air-fuel control. This kit is sold as a pair and covers many Chrysler Group V6 and V8 engine applications—confirm fitment by year and part number before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and engines will these sensors fit?\u003c\/h3\u003e\n\u003cp\u003eBLPextrm designed this O2 sensor pair to be compatible with numerous Chrysler, Dodge, Jeep and Ram models. Coverage includes both upstream (pre-catalytic converter) and downstream (post-catalytic converter) positions across multiple engine displacements. Always compare the listed replacement part numbers or your existing sensor to ensure a correct match.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible models: Chrysler 200, 300, Pacifica, Town \u0026amp; Country; Dodge Charger, Challenger, Durango, Grand Caravan; Jeep Grand Cherokee, Wrangler; Ram 1500\/2500.\u003c\/li\u003e\n  \u003cli\u003eEngine sizes: 3.6L, 5.7L, 6.4L across model years primarily 2004–2020 where specified.\u003c\/li\u003e\n  \u003cli\u003eCross-reference numbers: includes 56029084AA, 56041698AA, 234-4587, 234-4593, 234-4653 and many OEM\/aftermarket codes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does a replacement O2 sensor affect driving performance?\u003c\/h3\u003e\n\u003cp\u003eOxygen sensors provide the engine computer with data to balance fuel and air for combustion. Replacing worn or failing sensors helps the ECU regain accurate closed-loop control, which can stabilize idle, reduce roughness and support smoother acceleration—though results depend on the vehicle’s overall condition.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRestores correct air–fuel ratio feedback to the engine computer.\u003c\/li\u003e\n  \u003cli\u003eCan improve idle stability and reduce hesitations under load.\u003c\/li\u003e\n  \u003cli\u003eSupports proper catalytic converter monitoring by the downstream sensor.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the technical features and construction details?\u003c\/h3\u003e\n\u003cp\u003eThis BLPextrm pair uses a stainless-steel shell and a platinum electrode protected by an aluminum-oxide trap (capture) layer.
