NGK Mercedes-Benz SLK230 1999-1998 Direct Fit Oxygen Sensor

This is an NGK oxygen sensor, part number 25567. It's designed to be a direct fit for a wide range of Mercedes-Benz vehicles, including models like the C280, E320, and S420. Oxygen sensors are a crucial part of your vehicle's onboard diagnostic system. They send constant feedback to the engine control unit (ECU) to help manage the air-fuel ratio, which is key for keeping your engine running smoothly, maximizing your fuel economy, and reducing harmful emissions. If your check engine light is on, an oxygen sensor could be the culprit, often indicating issues with fuel delivery or the catalytic converter.

NGK, a major supplier of OEM oxygen sensors, uses advanced technology in their manufacturing. The ceramic element in this sensor features a three-stage plasma jet and deposit trap overcoat. This design helps shield the sensor from contaminants that can cause it to fail prematurely, ensuring it can do its job effectively for longer. Because NGK works closely with OEM manufacturers from concept through production, you can trust their sensors to perform as expected.
