I just replaced all the spark plugs in my car because i had a little miss when cruising in overdrive. I figured i would go all out and get really good ones (high performance i guess) since i'm in the process of making it go faster with performance mods from LMS and various other sources. Anyways besides the point I asked myself "do sparkplugs that got prongs actually help at all?" Doesn't electricity always find the ground? Like wouldnt one prong be a little more grounded the the other 3 (for example a on the +4 platinums from bosch) Electricity should know what one is grounded more. Or are all the prongs perfect on a spark plug? The particular sparkplugs that i bought were the new IR Fusion platinums from Bosch. The supposed to be performance i guess. :) anyways, these were just a few ideas that i was wondering about.
 
Apparently BOSCH gan blow right out of the head.... I just took mine out, it was amazing how easily they threaded out.

The ONLY "performance" plug is an Autolite 764. They are also the cheapest you can get.

You are right, only one ground will be used so one of those tips will be more favored. Also, the other will block the fuel mixture from getting to the spark as easily.

As for why 764s are best? Simple 5th grade physics. Copper is by far the best conductor to be used in the engine environment. Gold and silver would be better, but would not hold up. Copper plugs, however, should be changed about once a year or every 15-20k. All other metals, like iridium, do not conduct electricity as well. The ONLY plus side is that they last longer.

So if you want performance, Autolite 764.
 
I use motorcraft awsfa 22 C
one step colder than stock and is Copper {that is what the C stands for)

similar as the autolite 764 but is an actual motorcraft part.

Just FYI
 
NEVER NEVER use bosch......disaster waiting to happen.. motorcraft all the way!!!
 
u r right deepreaper, different plug with different designs dont really make more power. The more prongs there is, the more plug life. Also, the harder the tip the longer the plug life. Copper would need to be changed every year or so, wouldnt ya think. I have never had any blow out problems with my iridium. If you have nitrous or a supercharger than you need more spark, but than at that time i would get msd dis
 
these are all very valid points. i havent heard much about a plug blowing clean out of the head, but wouldn't that have to do with the thread pattern or the design, sumthing of that nature. all the plugs have to have the same thread pattern in order to fit into that particular motor.
 
also do the spark plugs really make a differance in how hot the spark is? cause ideally the hotter the spark the more performance. I know if u upgrade wires and distributer that helps as far as spark goes.

nope, with the Bosch plugs the porcelain blows out (or sucked in) of the metal threaded part of the plug. it has happened to some on here, my t bird sucked one in, ive seen countless fords at work with Bosch blow outs, actually just had a ranger the other day, melted the plug wire, coil pack, wiring harness to the coil pack, etc. it needed $500 just in parts!! not to mention how much i cost, and i aint cheep!
