if Jack Or Steve,or anyone else could please clarifiy. i have 99', 89's, 9's, could someone please tell me what these plugs are from hottest to coldest. thanks very much for the help,mike.
 
Mike 89 are cold as thy get in OD and 99 are one step hotter. 9 are like a MC9

I found the 99 where good in the .45 and up eng on 50%+ nitro.

89 just did not rev as high for some reason on my eng. Left the fuel unburnt and need to lean on it to much.

hi dave,sorry for late reply.so basically i need to run 99's in everything i got.thanks dave and to all who replied,mike.
 
what are the 003 plugs like and what size motor and nitro are they good for?
I do believe those are the Blues.
I use them on our Sport 20 and Sport 40 and there fantastic plugs.

My Uncle uses it on his 1/8th scale and has had good luck. I haven't had any luck with the Blues on Scale.

The 289 is comparable to them also.
