Issues as in memebers being out hundreds of dollars of money with no parts in hand and no refunds. Issues as in taking people share of event profits and running with them. As for the spark plugs just use whatever oem brand/type that came in your car. They were in there to begin with for a reason, I bet if you take out your stock pulgs right now you will see that they aren't just some no name bottom of the line plug. You may get a better spark by upgrading, but is there really truly a better spark? A spark is a spark am I not right? The whole s*** just blows up in the chamber anyways, if its not broke... don't try to fix it.
PS. Dont be suprised if this thread gets a make over or possible deleted
