A-Premium O2 Oxygen Sensor Set for Chrysler Dodge Jeep Ram – Heated 4-Wire, Threaded 2-Pack

A-Premium O2 Oxygen Sensor is a direct-fit, heated threaded oxygen sensor sold as a two-piece set engineered to restore accurate air-fuel monitoring on compatible Chrysler, Dodge, Jeep, Ram, Mercedes-Benz and Volkswagen Routan models.

When the engine control module receives incorrect oxygen readings from a failing sensor, performance, fuel economy and emissions control can suffer. This A-Premium replacement sensor arrives as a boxed pair with a female connector, four wires and a threaded mounting design so you can swap it into vehicles that use the specified reference numbers without cutting or splicing. It’s intended to match OE-style fitment across a wide range of model years to simplify installation and get the exhaust monitoring system working reliably again.

How is this sensor built and what specifications matter?

The A-Premium replacement is a heated oxygen sensor with four wires and a threaded mounting collar, sold as a set of two and shipped in protective boxes. The female connector and OE-style wiring make it suitable for plug-and-play installation on vehicles that expect a four-wire heated sensor.

• Wire quantity: 4 (heated sensor with heater circuit)
• Mounting: threaded for standard oxygen sensor ports
• Connector: female factory-style plug for direct connection
• Package: 2x sensors included per box

Will these sensors resolve check-engine lights and drivability issues?

Replacing a worn oxygen sensor with this direct-fit unit can clear O2-related diagnostic trouble codes and help the engine management system return to correct fuel trim adjustments. However, diagnosis is important: codes may indicate wiring, exhaust leaks or other components that also need attention.

• Common fix for codes referencing oxygen sensor circuit or bank sensor readings
• Works best when exhaust and wiring are intact and the engine has no unrelated faults
• Use an OBD-II scanner to confirm code origin before replacing sensors

What reference numbers and part details should I check before buying?

Confirm one of the provided reference numbers or cross-check with your vehicle’s OEM part to ensure match. This listing includes three commonly referenced part IDs and the sensor’s key physical characteristics to make verification straightforward.
