NGK Audi A8 Quattro 2007-2005 Direct Fit 5-Wire Wideband A/F Sensor

NGK is known worldwide as the largest supplier and manufacturer of original equipment oxygen sensors. This wideband air-fuel ratio sensor, part number 24316, is designed to work with a range of vehicles, including models like the Audi A8 Quattro, BMW 545i, and Buick LaCrosse, helping to keep your engine running smoothly.

Oxygen sensors are a key part of your vehicle's diagnostic system. Unlike standard sensors that just tell the computer if the mix is rich or lean, this wideband sensor gives a precise reading of the air-fuel mixture. This allows the engine control unit (ECU) to make exact adjustments, keeping combustion as efficient as possible, which helps maximize fuel economy and reduce emissions. NGK uses advanced ceramic technology, giving them full control over the sensor element from start to finish. This particular sensor features an advanced ceramic element with a three-stage coating that resists contaminants and protects against poisoning, helping to ensure reliable performance.
