Need glow plug advice

[modified]

I have the stock 5.9 mill in my savage xl.

Just broke it in last week using the hpi R5 glow plug that came with it.

Should i keep using the hpi R5 glow plug or should i change to a better one?

Any suggestions on a plug that will work good with this mill ? :Mr.confused:

I used an OS no7 Medium Hot when the atmospere temps were 50-60 degrees. With the stock air filter the motor needed more air flow and no7 plug worked best for me.

McCoy MC #8 is the best all purpose plug I have found, I have tried many and always come back to the MC's.
