As you start to turn up with the wick with timing and boost, it's important to run a cooler plug with a reduced gap. The stock plugs are gapped anywhere from .041- to .047-inch, but Evolution installed a fresh set of NGK TR-6 plugs to get the party started. For stock boost levels, they would normally gap the plugs at .032-inch, but they went ahead and moved them down to .030-inch in anticipation of more boost. Be sure to disconnect the battery before you swap plugs to ensure that you don't pop a fuse.
