The NGK direct-fit oxygen sensor for Hyundai Elantra (2011–2016) supplies OE-style closed-loop air-fuel feedback to the ECU to help maintain engine performance, fuel economy and emissions standards. Built by NTK, a ceramics-focused OEM sensor supplier, the unit uses an advanced ceramic element with a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to protect against element poisoning and improve longevity.
