Spark plug measurement!!!

06 400EX

I know the socket size is 18 mm. I need the outer diameter of the threads. I was told its either 10 or 14mm. I really don't want to pull mine until I get the air cooled sensor from Trailtech. I've been waiting on the production of the sensor for a few months.


Thanks for any info.

It's 12mm. NGK plugs that start with a "B" are 14mm, "C" are 10mm, and "D" are 12mm.


Let us know how the sensor works. I've wondered about that type of temp sensor.

Thanks for the correction. They were out of the 12mm at the moment. Only issue I've had with my Vapor is crazy readings on the speedometer. I was told the water is getting past the wire where it feeds through the connector body. (Not at the actual connecting point. After it dries out speedo returns back to normal. *Quick fix silicone* But i like the idea of using heat shrink tubing with a touch of silicone.

Oh and the display is kinda hard to read with a GLOB of mud on it, hehe.
