O2 Sensor Thread Size?

[CvSisinthehouse]

Does anyone know this? I cant figure it out and cant exactly take it off and take to the store. I bought an M10 and it was too small, bought an M12 1.75 and the threads weren't right. Thanks for any help.

Standard O2 sensor thread is M18x 1.5

 

[R-III-R Turbo]

Rocket sensor is M18 x 1.5mm as above

Sorry I meant Rocket III.

Rocket 3, presuming you have a stock exhaust, sensor is listed as M12. Don't know the pitch though.. you could measure the distance from the top of one thread to the next, when viewed from the side.
It will be 1.25mm or most likely 1.5mm, since you've tried 1.75mm.

The M12 nut I bought didnt even fit over the sensor tip if I remember correctly.

OK so I bought some M18 x 1.5 nuts and they are much too big. Or did they send me the wrong size? Cars are typically bigger than bikes right? Wow this seems complicated

take your sensor to the hardware and find the correct size
guessing 14 x 1.5
