I bought my engine for my T-Maxx used and the guy I bought it from gave me a bunch of glow plugs. I was looking at some of them tonight and they all had different numbers ranging from 5,6,7 and 8. What are the different #'s for?
Thanks.
I think they are the different heat ranges on the plugs. That was the way hpi was. I can't recall which was which. I think the higher number was a colder plug.
Peace!
