What you are suggesting would extend the life on single platinum
plugs. One thing to notice, however. If you pay close attention to
the OEM Motorcraft plugs, they are single platinum!! But, the plugs in one bank have a different letter suffix in the P/N than the
plugs in the other bank. This is because the outer electrode is
platinum on one plug P/N, while the center electrode is platinum
in the other plug P/N.....So, if the plugs are pulled, and
re-installed, it's important to put the plugs back into the same
bank that they came out of.....
Jim, you are 100% correct!!!, its good to see people that know what their talking about, Bravo!!!, by the way, im Tim, i just joined, looking forward to the fun here.

Have an 89 Ranger SuperCab with the 2.9 L, three years ago, now 65,000 miles later decided it was time to change out the plugs. They were Autolite single platinum and the engine was running fine. It has a coil and distributor. The plugs had light tan deposits, light to moderate rounding of the center electrodes, but the gap had increased from the original 0.044 to a little over 0.080 inch. This time I went with double platinum before I read this thread. Is that an excessive increase in gap for the mileage? Even if the double platinums are not "necessary" got them for $2.74 per plug after rebate, so in theory they should last longer with less gap erosion. I have a little over 137,000 on the truck so maybe the plugs will outlive it. Though I have yet to check, seems like I am getting better gas mileage which is nice in the current climate of $3.00 plus per gallon gas.
Hey all, I just wanted to share a great $$$$$ saver for you. I changed to Autolite Doulbe Platinum plugs and Autolite Professional wires. Guys, these things are hot! I won't be putting anything else on my Ranger. And for $4 a plug and about $30 for wires you can't beat it. And just a tip, if you have the EDIS system and use single platinums, you are wasting your money. With the unique firing of an EDIS single platinum causes EXCESSIVE wear on the plug. Do it right, do it once.
should I use double platinum plugs on my 2000 f/ranger?

It will be hard to find DP's these days, both Motorcraft and Autolite make "fine wire" platinum plugs which are now recommended by Ford as OEM replacments.
whil e the ngks blow in a good ole ford or chebby they plain and simpply are the best thing i have ever had in my nissan or my honda. i think it's more that the plug wasn't designed for the ford but someone figured out "hey this plug fits that hole!!!"

I've heard that the original plugs that Ford used in the 3.0 V-6's are too hot. Can anyone tell me the correct plug #'s I need for my '98 Rord Ranger with the 3.0 V-6? This truck is not a FFV engine. I would prefer the (Autolite part #'s). Right now the Autolites that I am using are the 764's and look like they are running just a " little bit" on the hot side. Any info. on this topic would be greatly appreciated.
Found this thread yesterday. I concur with the information on the Bosch plugs. I installed Platinum 4+ (I think they are called) at 25K miles on my '03 Ranger FFV. After reading this thread today I changed my plugs to Autolite APP104 dual platinum at 60K miles. The curb side Bosch plugs I took out looked very good, the center electrode looked normal. The road side plugs looked like the center electrode was split into several threads. I had noticed my truck was not accelerating like it had been. I was attributing this to the tranny because I have had problems with Ford trannys before. I started and idled it today after the change but I won't be able to run it until tomorrow.
Forgive the ignorance guys but I'm getting a little confused about the dual bank statements.
With respect to my engine 2004 3.0 FFV, this obviously doesn't have dual spark plug banks. Since my 3.0 had the coil pack ignition, is this DIS or EDIS? Not real clear on the difference with respect to my 3.0.
Since I do not have dual spark plugs banks, am I correct that the Double Platinum plugs are still recommended for my engine?
Thanks,
CMOS

Having "dual spark plug banks" (like the 2.3L) means simply that the ignition system fires two spark plugs per cylinder. That is why the 4 banger has 8 spark plugs total.
Having a "waste spark" ignition means something else - that one coil fires two seperate cylinders at the same time. That is why a V6 with DIS/EDIS (like your '03 3.0L) will be equipped with a single coilpack that contains three coils.
Here is my two cents worth on what may be happening here. Electrons repel each other. So it you have the spark jump from the tip to the electrode, you get a good even spark, but when you reverse the polarity, the design acts a little bit like an old fashoin radio tube, like a diode basically. It won't stop the flow of current, but it would increase the resistance across the gap in that direction. Its not unlike having too large a gap.
I seem to be a exception , I have Bosch dual platinums and my mileage and power fall perfectly into what a truck with my gears and tires should get. Now I put in a set of NGK single plats to try them and OMG, the worst mileage ever!
man i will tell you all i am SOLD on the platnium plugs and wires.
i was getting 120 miles to 20 dollars of fuel. rough starts (which is going away) wierd idle and rough at times, loss of power above 3k and put less than 20k on the bosche plugs and wires (spent alot on them)
i put the plugs n wires on yesterday and WOW. i got my power back through every gear and i mean passing power too in 5th!!! my miles JUMPED up per gallon like crazy!
