I'm sure this subject has been kicked around for a long time, but I would like to know what most of you guys do.
Building a RV-14A with a IO-390 engine hung in it. Coming from the old school (I was an Army aircraft mechanic in the late 1950's) I had not even considered using automotive spark plugs in a Lycoming engine ? mercy! However there seems to be a lot of discussion on VAF about plugs and it's hard to sort through all the posts.
My IO390 will have one P-mag and one standard magneto if that makes any difference. Auto plugs would certainly be much cheaper than aviation plugs but I don't want to paint myself into a corner.
