Bill, it's nice to hear a trustworthy opinion. I have been learning that some of the first mods i made to my truck years ago were not necessarily smart investments. I have bosch platinum +4 plugs and accel coil packs. I will most likely change back to motorcraft plugs in the next 10k miles, since most dislike the bosch on the tritons. Some on the other forums are insisting that these two items are actually putting my engine in jeopardy. Is it that bad or should i swith back asap? Honestly i never noticed any real difference after installing those items. Perhaps it is affecting mileage?
