Product Description

The NGK 25217 is an OE-type heated oxygen sensor designed for specific Kia Sedona and Hyundai Genesis Coupe applications. It serves as the upstream Bank 1 Sensor 1 position on 2011-2012 Kia Sedona models with the 3.5L V6 and the upstream Bank 2 Sensor 1 position on 2013-2016 Hyundai Genesis Coupe models equipped with the 3.8L V6. The application-specific connector and threaded body allow direct installation into the factory exhaust location.

The sensor uses a four-wire heated narrow-band zirconia sensing element with an 11.75-inch wiring harness. NGK/NTK's dual-coated platinum interface is designed for rapid light-off and response, while the contaminant-resistant ceramic element helps protect against deposits and sensor poisoning. The OE-style water-resistant connector provides a direct electrical connection without cutting or splicing the factory harness.

Because the same NGK part number serves different sensor positions across these two vehicle applications, correct identification of the vehicle, engine, bank, and sensor position is essential. For the Sedona, 25217 is B1S1/upstream right; for the Genesis Coupe 3.8L, it is B2S1/upstream left. The sensor is sold individually, with 1x required for the specified position.
