You Connedrod have made some wild comment I have zero idea about - stop making vague comments and only comments that are easy to follow ( in relation to this post what the hell is the plastic manufacturer? I have no got dam idea on your comment nor I assume most people) or simply don't post.
I think all my posts here are clear and they are all based on observation over some years (that is also clear I think - if I need to spell that out, I give up).
Plastic fantastic is a term, used by people not qualified to work on them, to describe composite aircraft. Cirrus is one such manufacturer. Cirrus use lean assist, so I assume he is talking about Cirrus aircraft. There is a Service letter advising Cirrus owners who have fitted an aftermarket Turbo to not use fine wire spark plugs. I don’t think Cirrus have said you shouldn’t use fine wire plugs on their standard aircraft.
