NGK BMW 318i 1999-1996 Direct Fit Oxygen Sensor

This NGK oxygen sensor is designed as a direct fit for your 1996-1998 BMW 318i, 1996-1997 318is, 1996-1999 318ti, 1998-2001 750iL, and 2000-2004 X5. As a crucial part of your vehicle's diagnostic system, oxygen sensors monitor the air-fuel ratio by sending feedback to the engine control unit (ECU). This helps ensure your engine runs efficiently, maximizes fuel economy, and keeps harmful emissions in check. When an oxygen sensor isn't working right, your OBDII system will often alert you to potential issues with fuel delivery or the catalytic converter.

NGK, a major supplier of OEM oxygen sensors, builds these units with an advanced ceramic sensor element. This element features a three-stage contaminant-resistant plasma jet and a deposit trap overcoat. This design helps protect the sensor from poisoning, which can lead to premature failure. NGK works closely with OEM manufacturers throughout the development process, from initial concept to final production, to ensure excellent performance and improved resistance to common failure points.
