peevee Posted July 20, 2017 Report Share Posted July 20, 2017 Title says it all. We've been waiting until about 75 to 100, that might be too much. Quote Link to comment Share on other sites More sharing options...

peevee Posted July 20, 2017 Author Report Share Posted July 20, 2017 Fairly sure ours are fine wire. I don't think anyone would put massives in a turbo but you never know. I'll know for sure when I clean them. I'll stick to twoce a year, once at annual and once mid way I guess. Quote Link to comment Share on other sites More sharing options...
Hank Posted July 20, 2017 Report Share Posted July 20, 2017 I do my massives every annual, and sometimes check them at oil change in between. Since moving to a field with no services, I no longer have access to a plug tester, so the best I can do is clean and gap them right now.

Sent from my LG-US996 using Tapatalk Agree. I spend a good amount of time cleaning and inspecting them yearly, and replace any having cracks in their ceramic cores. Also no need to rotate iridium fine wires. You pretty much put them in and they just...work. :-) 1 Quote Link to comment Share on other sites More sharing options...
peevee Posted July 20, 2017 Author Report Share Posted July 20, 2017 Well, I'll get the p/n and if they're fine wires maybe just leave them be Quote Link to comment Share on other sites More sharing options...

If I were running massives I might have to invest in a resistance tester! Quote Link to comment Share on other sites More sharing options...
Hank Posted July 20, 2017 Report Share Posted July 20, 2017 Multimeters are fine, the "Plug tester" that I no longer have access to checks their ability to produce spark with compressed air blowing across them, from the same air supply that the other side of the tester uses to blast glass beads into the electrode and then clean the glass beads out. One big box, with two places to screw in a spark plug [clean, then test]. 1 Quote Link to comment Share on other sites More sharing options...
blaine beaven Posted July 29, 2017 Report Share Posted July 29, 2017 I clean and rotate my massives at 50hrs. I do about 75-100 hrs a year. I've only had my plane for 3 years, but judging by what's in the logbooks the spark plugs have 700hrs in them, and seem to be in great shape.
