Plugs from my P3. At Mid-Ohio during practice, I missed a shirt. Sometime around then the motor started smoking when I got off the gas.

Motor is left to right 1-4
#1 was dry, black & sooty
#2 was wet, black and oily with oil on the plug threads
#3 was dry, black & sooty
#4 was wet, black and oily with oil on the plug threads
very odd that #1 & 3 were the same and that #2 & 4 were the same
