You can compare yours to the new V2 and check the descriptions:

 

https://odonnellglow...mparison-chart/

 

99 = 288

 

89 = 289

 

9 = 9

 

288 is hotter than the 289, where the 9 fits in I'm not sure but it doesn't have the great seal the others do...

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.

Ooops, my mistake!  The 89 compares to the new 289 and so the 288 would be hotter.

 

Edited!

Chart says they compare to the 287 which I like a lot.

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.
