Walker downstream oxygen sensor, UPC 450048755767, sku-17147850744, is listed under Exhaust Parts & Emissions Parts. It is listed for Hyundai Accent, Elantra GT, Ioniq, Kona, Sonata, Tucson and Veloster models with 1.4L, 1.6L or 2.0L L4 engines from 2012 to 2022.

Its sensing element has an integrated heater that reaches operating temperature in seconds, helping the engine enter closed-loop operation sooner and reducing cold-start time. The sensor has a protective coating and is described as having one of the fastest activation times in the industry. It is designed to meet OE standards within close tolerances.

A damage-tolerant housing protects the ceramic element from silicone and lead poisoning; porous PTFE admits atmospheric oxygen while keeping water and engine grime out of the casing. Walker Products also makes fuel injectors, throttle position sensors and other fuel-system components designed for engine efficiency and performance.

The company cites years of experience making automotive parts, the trust of professional mechanics and DIY users, and customer support.
