I can purchase a three wire Zircona type sensors for very little money and fit my existing plugs onto them by soldering. Question is, are these the correct type. The thread size is 18mm and the spanner size is 22mm. It does state they will not replace “Titania” or “Planar” type Sensors. Full details below.
So am I onto a good thing here or not?This is a 3 Wire universal sensor for a Petrol Engine. The best way to determine if it will fit your car is to count the number and colours of the wires on your existing sensor. Basically, if your existing sensor has the same number and colour of wires 2 White, 1 Black in this case, then you can be 95% certain that this sensor will do the job. For the more technically minded this is a Zircona type sensor (see below for explaination).The thread size is 18mm and the spanner size is 22mm. This sensor will not replace “Titania” or “Planar” type Sensors.
