NGK Peugeot 405 1991-1989 Direct Fit Oxygen Sensor

This NGK oxygen sensor is a direct fit for your 1989-1991 Peugeot 405. It's a crucial part of your car's onboard diagnostic system, helping to keep the engine running at its best. By providing constant feedback to the engine control unit (ECU), it helps manage the air-fuel mixture for optimal performance, better gas mileage, and fewer emissions. If your check engine light is on, this sensor could be the culprit, alerting you to issues with fuel delivery or the catalytic converter.

NGK, a well-known name in ignition and sensor technology, builds this sensor with an advanced ceramic element. This element features a three-stage protective coating that acts as a plasma jet and deposit trap. This design helps shield the sensor from contaminants that can cause it to fail prematurely, ensuring it works reliably over time. As the world's largest supplier of OEM oxygen sensors, NTK brings a lot of experience to their designs, working with manufacturers from the start of development.
