Popular plug for 97 2.3?

[fastpakr]

the platinums are an iridium plug

No - Platinum and Iridium are completely different metals/plugs.

I do understand they are different plug names, and that they are different metals, but the iridiums do contain platinum.

the spark does not go "all over the place" the plugs go from outter to inner electrode and thats it. witch ever outter electrode is close will fire, the multi point plugs make no difference than a single electrode plug....

+1 the spark is only going to jump 1 gap.

bosch makes excellent products dont get me wrong, but the multielectrode plugs of any make (splitfire etc) cause ignition timing problems in stock ignitions cuz the spark is going all over the place, .

Huh???

another ignition issue ive run into is running IRIDIUM tipped plugs in ignitions that dont call for it. iridium is very resistent to corrosion of the tip, but is also a hellacious resistor to spark, unless your ignition is cranking some volts (which ford does not) its not recommended to run these. the same buddy w/ the same camaro put these in thinking it would help, the car did run w/ them. however, 3 months later he had to change the computer, and smoked 3 coilpacks. when the new computer was installed he noticed that after running 10 miles you couldnt touch the damn thing, took it to the shop and they said the plugs were pulling so much voltage throughout the system it caused voltage drop and shorted the system.

bosch makes good o2 sensors injectors and standard/platinum plugs, the platinum 4s and other multielectrode plugs do more harm than good and are a waste of money.

what i mean by jumping all over the place is going from center electrode to another electrode, then trying to jump 2 gaps (poorly) then going to another gap on the other side and so on. when you put them in a trk bike or boat (ive seen this in all 3) cuz the spark is acting stupid youll turn over for 30 mins then a sharp backfire. reinstall factory recommended plugs it will fire up first time.

it is not recommended to run iridium plugs unless you close up the gap or install a higher voltage ignition because of so much current draw to get them to jump the gap, i had a peak ignition meter and seen this. normally under load when a vehicle warms up it has to jump so many millimeters, and w/ normal plugs it will do this. the iridium tip plugs since they pull more voltage will not allow the system to arc at the proper gap or if they do its weak from system strain. upon closing the gap they act normal but you lose flamefront size which could lead to other problems. (rich unburnt mix) this is what ive found when diagnosing ign problems over the years.

That doesn't make sense. To jump both gaps at the same time there would have to be almost equal resistance for each electrode. The possibility of that is statistically small. And even if that DID happen, you would have the same voltage across each gap (but only half the current).

http://en.wikipedia.org/wiki/Current_divider

Igniting the gas doesn't take current, it just takes a spark, so it doesn't matter if the current is halved across the two sparks. Regardless, the more likely scenario is that one gap has less resistance than the other, and thus the spark occurs in that gap because electricity goes the path of least resistance.

yes all it needs is a spark, but w/o enuff voltage to arc at the right time is the problem, weak spark can be several degrees off and cause backfiring/preignition or late ignition, causing the engine not to run. you have spark but at the wrong time, causing problems.

You need to take a good course in automotive ignitions. Constructive criticism, not a flame.shady
