Hyundai Elantra / Tucson / Sonata / Kia Forte / Optima / Soul Upstream Oxygen Se
$44.99
The upstream oxygen sensor measures exhaust oxygen content before the catalytic converter, letting the engine computer fine-tune the air-fuel mixture in real time. A worn sensor typically causes reduced fuel economy, rough running, and a check engine light.
This sensor (OE 39210-2E101) fits Hyundai Elantra, Sonata, and Tucson 2.0L/2.4L GDI engines, with shared applications across Kia Forte, Optima, and Soul models. It uses the factory wiring connector for a straightforward, plug-and-play install.
Built to OEM voltage and response specifications, it restores precise fuel trim control, helping the engine run cleaner and more efficiently.
