I use stock bosch copper plugs. They work fine and there really is no reason to use anything else unless you have a turbo/supercharge upgrade. Some people who are chipped have gapped their plugs dirfferently to make them a step colder, and some go with platinum plugs.

I am chipped and tried different plugs but noticed no difference. Platinum plugs are made for durability, not for performance. Don't let the cool factor fool ya.<img border="0" src=smileys/smiley1.gif border="0">
