Default Sirio S21 CL3B - Glow Plugs

What are the best plugs to use in the Sirio S21 CL3B? I think this motor comes with the standard head.

O'Donnell OD99, McCoy MC-8 (med) or MC-9 (cold). These all work pretty well on 30% fuel.

If it's standard, the above recommendations are great. If it's a turbo, Sirio 5 or 6. Sirio turbo plugs are fantastic.

Looky looky what I saw in the for sale section! For this price, buy 10, these will run you $6+ each in stores.

I would suggest you get a turbo head button from a CL7B. You'll see a big difference in engine performance and economy.It just runs better with a turbo plug.

You want the Sirio standard plug #6. Its a medium plug. #5 is hot. #7 is cold.

The turbo head button does not fit. It a mm or two too big.

The .21 button should fit. The .24's and .28's are bigger. But then I haven't tried so I could be wrong.
