NGK BMW 735i 1987-1986 Direct Fit Oxygen Sensor

When you're looking to get your 1986 or 1987 BMW 735i running smoothly again, a new oxygen sensor is often the key. This part is crucial for your car's on-board diagnostic system, helping to keep the engine running at its best, maximizing your gas mileage, and keeping those emissions in check. It constantly sends information back to the car's computer to fine-tune the air-fuel mixture and can even alert you if there's an issue with the fuel system or catalytic converter.

NGK, a major supplier of original equipment sensors, builds these with an advanced ceramic element. This element has a special coating that helps protect it from contaminants and deposits, which can often lead to sensor failure. Because they control the ceramic element from the raw material all the way to the finished product, they have a solid understanding of how to make these sensors reliable.
