Spark Plug Thread Size for M20

[Mordan]

Hi

I like the idea of using a whistle to set piston to TDC

just don't know the thread size of a spark plug

this one is 14 mm (metric). Will it fit my M20 engine?

NO parts or tools are required to set the engine to TDC. If you have the Bentley manual, the procedure is described in detail in there.
