What are our options for plugs these days?
Seems people frantically buy McCoy when they pop up, I prefer O'Donnell.
What are you using that's available and in what engine, fuel % combination?
Is O'Donnell still making plugs?
 
I’ve been using 289/289T’s in all my engines .21-1.01 on 40%-60% nitro with 18% oil.
I have some of Al’s Rossi plugs to try but haven’t yet.
Are they similar to the gold plugs, I think they were 09's?
 
Has anyone ran Al's plugs ?. I have a bunch I ordered last year but haven't had a chance to try them out. I think they are r5 and r6 The elements look thick compared to my OS #8 plugs. I am hoping they work good on my 21 engines which is mainly what I like running.

The R5 is a great .21 plug
The R6 for .45 and up
 
The R4 is a good .21 plug as is the R5. With that low of nitro the R4 may be better for you.
I have some engines that have the turbo head and he only had rt5 . I might have to sell these and find a different plug if they don't work. hmm
 
A couple of years ago I bought some Fox miracle plugs from my LHS. I needed a few plugs that weekend and that was the only plugs they have.

I do not race. Run 25% Omega. The Fox plugs worked well for me. FWIW

I am only fun running as well. 30 percent car fuel is easiest to find around here and I just add oil to it. I haven't found any high nitro in the Kansas city area yet. I don't think it exists here .
