Question about HPI .25

[403forbidden]

Can anyone tell me what glow plug works best in the HPI .25 engine?

I looked on the HPI site, bit it didn't address it. Thanks

I used a MC59 with no problems.

Also the O.S. #8 works well for that engine.

MC59 but remember weather and percentage fuel has a big play in what temp plug to use. The MC59 is a hot plug.

I have found OS 8 to work very good when I had my S-25 in my Savage SS
