Just one question. What's the difference between warm up plugs and race plugs?

We keep an old set for the first fire up at an event. Mark "pickles" the motor after an event if we are not going to run for a bit and we put the old plugs in so that we don't foul the race plugs with any oil that is still in the top end of the motor. Spinning it to get oil pressure (with the plugs out) usually does the job but the old plugs are a bit of insurance.

Back when I used to run TAD, we used a set of hotter champion N63DR plugs as warm up plugs. Our race plugs were N57DR. The thought was that the hotter plug would bring the engine up to temperature quicker during the warm up because of the hotter tip temperature. Eventually we stopped doing that (for cost reasons and limited benefits) and our warm up plugs eventually became what Roo described above.

Installed a set of NGK B9ES ($1.79 O'Reilys) at the beginning of the season, ran them all year long, following season pulled and tossed in the trash, installed new ones
