Ok, next up we have the spark plugs. RIPP recommends NGK in their manual (either copper or iridium, but not platinum). NAPA is the only store that regularly stocks them in my area. I was given the wrong size thread @ NAPA, and I didn't realize this till I pulled the stock ones outta my JK. Soooo I ended up gapping the stocks to .032 inches. Which turns out to be fine. I didn't know it but they come with Champion Iridium plugs from the factory. So first you unplug all 6 coils from the valve cover and carefully remove them. I found a slight upward pressure while carefully turning a 1/4 back and fourth was the easiest. I used a plug puller magnet to fetch the plugs out after loosening them up with a socket and extension. Then its as easy as gapping them down (they seemed to be about .035 stock). Then you just reinstall reversing the steps. The only plug that was difficult to access was the center plug on the passenger side.
