Overview

The Spectra Premium OS6181 is an upstream left oxygen sensor designed as an OE-style replacement for select Hyundai Genesis models from 2012-2014. This sensor is critical for emission control and optimal engine performance, monitoring exhaust oxygen content to provide data to the engine control system.

Positioned on bank 2, upstream of the catalytic converter, the OS6181 ensures accurate air-fuel mixture readings, contributes to reduced fuel economy, and helps prevent emission test failures. It is built to meet or exceed original equipment performance targets, addressing issues such as a check engine light related to oxygen sensor performance, rough idle, and hesitation linked to inaccurate exhaust monitoring.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
