Spark Plugs

Here it is, I have been thinking of replacing the plugs in my 02 SuperCrew 5.4. I have been thinking of going with the Bosch Platinum 4's. They come with a garuntee that they will improve fuel efficiency or your money back. I have the motorcraft platinum plugs in it now.

Does anyone on here have any experience with the platinum 4's? Any one have any experience with other plugs?

I can rember reading other threads on this before and the outcome was a spark can only jump one gap at a time. So there isn't much point in having a +2 or +4 sparkplug.

The ignition system on these newer Fords don't seem to like Bosch plugs. I have read many many complaints about misfires and such (too much work to keep replacing plugs on these engines).
Autolite or Motorcraft Double Platinums are the only way to go.
