Spark Plug Data
 

Where can a person find all the data about spark plugs thread size and types of seat available. Also is ok to fill in a deep nick in a taper seat in the cyl head. Or is it best to re-machine the seat...and use a flat sealing washer? Thanks Capt,n[X(] P.S. What size is the threads on a CM6 spark plug?

Hello cj

For CM6:

That is: Thread 10mm , Hex 16 mm, Heat 6

For me its best to think in reverse when it comes to plugs.
Measure first and then encode.
Buying is the hard part :)

Good luck
