So I was digging through my buddies left over RX7 parts and ran across his sparkplugs. From how he described operation, and its appearance, it seems to me they would provide more complete and even combustion, especially in a piston motor like ours. I'm just curious if anyone here has ever tried running them, or testing/analyzing them at all. I plan to take this thing into school with me today and give it some testing.
