    Glad I found this, as I was wondering aboug the age of the earlier advice, and why it didn't jive with my MM.  I wonder why the MM changed. Does this coincide with a change of recommended plug?

    The MM changed because the new $20 spark plugs are totally different to the good old $3 NGKs.

    Yes. Make sure you compare the same plugs. NGK vs Rotax plugs.

    Be careful here...the ROTAX branded spark plugs can not be changed for gap, only inspected.  See the correct MML, maintenace manual line, for the details.  The NGK have not been sold in new engines since 2017 and technically NGK are no longer approved for flight.  If you are buying aftermarket NGK be aware that they are at your own risk, NGK will not support them in any aircraft applications.  

    Cheers
