So, there's a picture someone from the honda-tech and pgmfi forums made for me about modifying your spark plugs for better efficiency, and it works for sure to boot!
Exactamente what he said:
DrDisco: take the stock plugs and modify them
DrDisco: lol
DrDisco: it will yield more benefit than indexing, and it's free
DrDisco: file the ground electrode so that it is only covering half of the center electrode when you look straight down on it
DrDisco: then round the edges, again looking straight down, so that it's like a semi-circle at the end
DrDisco: make the top and bottom edges (looking from the side) as square as you can
DrDisco: this is dyno proven stuff
