How is this sensor built and what are the key specs?

The A-Premium oxygen sensor supplied here is a heated, four-wire sensor with a threaded mounting style and a female electrical connector. It’s packaged as a set of two sensors in a box so you can replace both bank sensors where applicable or keep a spare on hand.

• Wire count: 4-wire heated sensor for faster warm-up and stable readings.
• Mounting: standard threaded installation compatible with factory ports.
• Connector: female electrical connector designed for plug-and-play with matching harnesses.
• Package: 2x oxygen sensors supplied in boxed packaging for protection and storage.

Will this oxygen sensor match my original part numbers?

You can verify fitment using the listed reference numbers included with the product. Reference numbers help confirm cross-compatibility with aftermarket and OEM replacements used in many service parts catalogs.

• Reference numbers provided: 4727446AD, 250-24253, 25024253 for cross-checking.
• Compare your vehicle’s existing sensor part number and connector type before purchase.
• Check whether the vehicle requires one or two sensors for your engine layout.

What should I expect during installation and performance?

Installation is typical for threaded oxygen sensors: remove the old sensor, confirm the mating connector and threads, and fit the new sensor to the factory port. The heated 4-wire design accelerates warm-up, so the engine control module receives usable data sooner after startup.

• Installation: standard threaded sensor replacement—use an oxygen sensor socket to avoid damage.
• Performance: heated element aids quicker operation in cold starts and stabilizes readings.
• Maintenance tip: inspect harnesses and threads for corrosion before installing to ensure a reliable seal.

Who is this for: This A-Premium 2-pack is ideal for DIY mechanics, independent shops and owners of the listed Chrysler, Dodge, Jeep, Ram and compatible models who need an affordable, direct-fit heated oxygen sensor replacement. If your vehicle’s diagnostics point to an oxygen sensor fault or you prefer replacing both sensors at once for consistent readings, this boxed pair provides an economical option. Always confirm fitment by year, model and existing sensor connector before ordering to ensure correct match and avoid returns.
