Volvo Oxygen Sensor 234-4451/30751865/30774651 corrosion-resistant long-term stable operation

This oxygen sensor is designed for Volvo S60 (2011-2018, 2.0T/2.4L), V60 (2012-2018, 2.0T), XC60 (2009-2017, 2.0T/3.0T), and S80 (2007-2016, 2.5T/3.2L); ensures precise monitoring of exhaust oxygen to optimize air-fuel ratio, improving fuel efficiency and reducing emissions. OEM numbers include 234-4451, 30751865, and 30774651 for cross-checking with original parts. Replacement difficulty: medium; use dedicated oxygen sensor socket to avoid thread damage; clean exhaust interface and apply anti-seize. Sensor uses corrosion-resistant coating for stable signal under long-term high temperature and chemical exposure; suitable for high-mileage vehicles to reduce future maintenance.
