I think so, thanks! But C7 plug was brown this morning final run. So I change to Odonell 99T plug, not much different in performance. I think I can lean it more, still a lot smoke. I love this engine lol

Thumbs up

Uriah, thanks for letting me try your new Murnan M21 last Sunday. As you could probably tell by my expression,"" the power it puts out compaired to my 35 +21 mod was overwhelming to say the least. Hands down, its the motor
I want in my car.

Thanks again, Steve

Default SIRIO PLUG

One of my friends has about a dozen of these Sirio plugs. He Told me these have been in his RC closet for at least 3-6 years.

My Question is are these the Quality of Sirio plugs of today?

I have a New IDM 21 From Murnan and need plugs and would rather have Sirio Plugs then Picco.

Has anyone seen these sirio plugs like this in black, packaged like this or have a factual based opinion. I have only seen the silver ones. They are the Turbo Cold plugs though.

Thanks for any input

Motor Looks great thanks Uriah

Does Odpnell 99T work on 35 plus well?

Not sure. The silver ones are my favorite plugs but never had the black ones.

Yes it will but will not last as long or run quite as crisp as a good plug (sirio, IDM, etc.)

If I am not mistaken the black plugs were for the buggies and the silver for circuit.

I was at Mikes Hobby shop in Porter Texas last weekend and ran the Black sirio #8 in my IDM Murnan .21 and it was flawless.


Uriah, Thanks for the Great Job on the IDM we took 2nd with that great power

Great Job! I'm glad you like the engine.

Those GT bodies are coming along. I have not seen that one before. It looks to have a good bit of downforce.
