A-Premium Oxygen Sensor O2 Replacement for Hyundai Genesis — Heated 4-Wire, 450mm Cable

A-Premium O2 oxygen sensor is a direct-fit replacement sensor engineered to restore proper exhaust monitoring for select Hyundai, Genesis and Kia engines.

This heated oxygen sensor (HO2S) from A-Premium replaces the factory unit to help your vehicle maintain accurate air-fuel feedback to the engine control module. Designed as a threaded, four-wire assembly with a 450 mm cable, it matches OE form and electrical configuration for straightforward swap-in installation on the listed models. The sensor is sold as a single boxed unit and includes common reference numbers to help you confirm fitment.

Which vehicles and positions does this A-Premium sensor fit?

The sensor covers a wide range of Hyundai, Genesis and Kia applications across both four-cylinder and V6 engines. Fitment varies by model year and mounting position (upstream/downstream, front/rear/right), so check vehicle specifics before purchase.

• Downstream fits: Hyundai Santa Fe, Sonata, Tucson; Kia Optima, Sorento, Sportage (selected years/engines).
• Specific downstream front/rear and upstream positions: Palisade, Sedona, Telluride, Cadenza, K900, Genesis (selected years).
• Reference numbers: 250-241283 and 250241283 to cross-check compatibility.

How does this sensor make installation simple for a DIYer or technician?

The A-Premium unit is built to OE-style dimensions and uses a threaded mounting with a female connector, so it plugs into existing wiring harnesses without splicing. Its heated element and four-wire design ensure it interfaces correctly with engine management systems that expect that configuration.

• Threaded mounting type for standard oxygen sensor sockets and wrenches.
• Four-conductor, 450 mm overall length cable for correct reach and orientation.
• Female connector matches original harness—no special tools or adapters required.

What are the construction and performance features to expect?

A-Premium manufactures this sensor from corrosion-resistant materials and incorporates a heated sensing element for quicker response after cold starts. While not a performance upgrade, the part is designed to meet typical longevity and responsiveness expectations for replacement oxygen sensors.

• Heated sensor type for faster activation and stable readings at lower temperatures.
• Durable construction intended to withstand exhaust system conditions.
• Supplied as a single boxed unit for protection during shipping and storage.
