I just bought a hpi firestorm and i want to make sure i take care of it so it lasts me a while. i haven't used it just have it all prepped up for break in tomorrow.. at the moment temps range from mid to high 30's to mid to high 50's and i have a mc coy 59 plug running 20% nitrotane fuel and i wanted to make sure that plug would be ok to run when the stock one dies because I'm sure it will sometime after break in because of the tuning. Anyway thanks in advance!
