At its heart, NGK is a ceramics company, and they use advanced technology to control the ceramic element in their oxygen sensors from start to finish. This particular sensor features an advanced ceramic element with a 3-stage coating designed to resist contaminants and protect against element poisoning. This focus on material science and continuous improvement means you get a sensor designed for excellent performance and resistance to common failure points. This sensor fits a range of vehicles, including models like the 2001 Saturn L100, 2000 Saturn LS1, and 2001 Saturn LW200.
