Well after weeks of screwing around with my 3.8l JK motor I finally found the problem. The Champion Double Platinum spark plugs do not work in my Jeep. I switched to the NGK V-Power plugs and that fixed my issue. Not only were the NGK plugs a fraction of the cost of the Champion Double Platinum spark plugs but they also don’t foul after 5 minutes of running. I will be publishing an article about this as well as the RIPP Superchargers header install and the High Voltage Screamin’ Demon Coil and LiveWires install.
