Bosche platinum
Just curious to what your thoughts may be on the bosche plugs with the four electrodes.
I was watching spike tv and that show "Trucks" was on, and the guy was praising them.
Anyone use them or have an opinion on em?

I haven't used the 4 electrode plugs, but I've heard of several people that used them and were unhappy. The main complaints were rough idle and pinging.
I've used the bosch platinum single electrodes on my 74 Bronco and could not distinguish any improvement over copper core plugs. I've had better luck with Autolite platinum and NGK U Groove plugs.
Beware of TV endorsements... always remember who pays their bills.

4 Electrode Plugs
The double and four electrode and split fire plugs in my humble opinion are sales gimmics. When a plug fires the electricity follows the path of least resistance and only fires off of one electrode.

I have the 2 pole Bosch platinums in my truck, however, I can't tell you how they perform as of yet, as I put them in to try and correct the bad vibrations and missing in my truck. It helped some, but not much. I think it is an injector in conjunction with a old fuel filter.

RE: ALL FANCY SPARK PLUG DESIGNS
Folks, remember, as stated already, that electricity will always follow the path of least resistance to ground, no matter how many possible paths there are. Standard plugs = 1 spark. Fancy plugs = 1 spark.
As for platinum. The only, and I mean only, advantage of platinum spark plugs is that they last longer. You'll notice that they've come about in the last few years, coincidentally, about the same time auto engineers got bold enough to design intake manifolds that have to be removed to change plugs....
Copper is actually a better conductor than platinum, so in any vehicle where it's relatively easy to change the plugs, just save yourself a couple of bucks, and get yourself some copper plugs that will actually probably perform better anyway... just not for as long.

I have used the bosch plugs for 20 years and never had a problem with them. I did have a problem with the split fire plugs.
The bosch plugs did not give me any increase in performance but the lifespan is greater than autolite, champion, ngk or others it have tried. The cost verses replacement time is worth the investment.
I had an Isuzu Trooper and had to replace the autolite, champion and AC about every 20,000 miles as well as the wires. With the bosch I replaced them about 60,000 miles and the wires lasted about the same.
Platinum is inert and will not erode as bad as other metals. Read some info about the Wright brothers and the engine they built for the 1903 flyer. The electrode tips were platinum for that reason. The actually touched to make a spark and any other metal would weld its self together.
