Dynamite Mach 427 glow plug

[Chickenwing]

I’ve finally got to break in my Mach 427 and wanting to get some spare glow plugs (still have a couple McCoy Mc-59’s) from years ago. I believe they no longer make them. What would be the best equivalent to the McCoy Mc-59?

lately i have been liking the dynamite platinum plugs, and the O.S. LC3 in my Losi Mach .26 and other long/standard type plug nitro engines.
Mccoy MC59 is a hot plug, so i would start with another hot plug as well.

I bought the OS A3's ,they are a hot plug ,but I think a medium will also work as well ,
MC 59's were great plugs ,I use to run those too back in the day!
If your engine is tuned pretty good ,a plug should last a long time ,however ,I know
that break-ins will foul them an if you keep running them too lean you will cook them!..

I've been running odonnell's 99s in mine, or I should say I was. I havent ran that kit in 5 or 6 years now.
