My ECI 0-360 has performed flawlessly for 280 hours until the last two flights, runup and mag check is fine after first start but after landing at the fly-in and sitting for an hour or so the left mag check runs rough. Tried clearing the plugs with no effect but when I got back home and did another mag check it was fine.
Tried the mag check in the air and #4 CHT falls so I assume this is the problem cylinder. Have not pulled the cowl and plugs yet but it got me thinking about the useful life of aircraft plugs (they are Champion and looked fine at the annual) and what the best plugs are to replace them with.
Appreciate inputs and plug recommendations ( no Pmag stuff as it is on the list at some time)
