+1 Stock plugs work great in the 9s for all kinds of setups. You really shouldn't have a hard time finding them... I know the Advance Auto here stocks them.

only when you increase compression do you need plugs... the oem plugs are amazing... anything else with "foul" out... basically they are so cold during combustion the carbon is able to build up on them til they just can't arc anymore...
