OK, I really probably should have looked here first and did a little research, but I had based my decision on having done this same thing to my wife's Geo Prizm with outstanding results. I figured if it worked for her car, it'd work for my truck. I put 16 Bosch Platinum +4 plugs in my Hemi. I've only had them in there a couple of days and so far the results are:
If I behave and drive conservatively, my gas mileage improves over what the truck did on stock plugs.
If I get throttle happy, th mileage sucks just as bad as it did before and I really can't tell any difference in performance yet, the truck is still plenty fast enough to get me into lots of trouble with the fuzz.
I just finished searching the archives here and found where people are getting misfire alerts in their Dodge vehicles in using these plugs. As of yet, I haven't suffered any such thing. The truck still runs fine. Did I screw up royally in going with the Bosch or will they suffice until it's time to change them again?
