I didn't see one on here, but alot of differing opinions. What brand, why?
We all know about the hassle in changing.
and my preference.

I use standard Bosch Platinums. See http://www.explorerforum.com/forums/showthread.php?s=&threadid=28183 for a technical reason why the +4's don't work any better than the regular Platinums.

Factory:D

Because I got the best wires on the market IMO. Champion Truck Wires. I just wanted to get the same brand plugs and wires.

Hmm guess I'm the only one running Autolite Platinums.

i use bosch 4+ plugs and wires and wiper blades from bosch cuz i get them free from a kid

I use Motorcraft.

I use NGK Platinums

I added one! I hope you dont mind? You left my plugs out. :)

I picked up some autolite platniums the other day. what do you think of them????

How do new spark plugs make a difference over factory?

Hi out there. Here in South Africa resources are limited and with our currency at an all time low, we look for the best deals! I have just fitted some Autolites copper core due to the Motocrafts being some 6 x more expensive! Could anybody help with the plug gap? I have set them according to Chilton's manual at 0.054". Is this correct? There seems to be some power loss and fuel consumption has gone up, but this could be due to the Emission system playing up, and that is another story!
Thanks:rolleyes:

Motorcraft.

Ive used alot of em. The AC Delco Rapid Fires, i think last way longer and offer all the performance THAT you can get from spark plugs. As far as +4's , electricity can only flow one way at a time, so you dont get 4 sparks you get one like the rest. They may last longer due to the four design.

when i took my spark plugs out, to put new bosch platnums in, they were black. but i didnt try to gap the new ones, should i have?

YOU ALWAYS GAP YOUR PLUGS!!!!!!!!!! Most come "PREGAPPED" but you can just imagine how that will go.:mad:

Regular Bosch Platinums for me.

I was thinking about getting Bosch +4s, should I also get new wires?

I just installed a set of Autolite platinum pros and a set of autolite wires, seems to run 100% :exp: :yelexp: :redexp:

NGK Platiniums in mine with Jacobs wires

I would rethink the +4s but by all means replace the wires too.

Good luck......

just bought bosch double platinums.....

i just installed Champion Truck Plugs with Taylor Spiro-Pro wires. What a hell of a difference this made to my 97,500 mile factory plugs and wires. Iwent with ths Champions because I have never had good luck with platinum plugs and I have never had a problem with Champions.

Motercraft and jacob wires:p

I still have the stocker's on mine. Don't get Bosch +4's, they're right, they don't work. A couple of people from industry have told me that they don't work any better. For what plugs cost, if they really worked that much better, don't you think that Ford would put them on stock vehicles? Just my $0.02.

I've got the Bosch Plat. +2. Thinking about trying some Denso Iridiums next time around. Otherwise Motorcraft plats.

i amazed no one has mentioned this yet...

but the copper ones outperform all the rest. only reason to use te others is if your lazy and want to never have to change them.

Question
My currant OEM plugs are motorcraft AGSF-22PP, am going to a mild nitrous program next month, all I can reaserch tells me to run a slightly cooler plug to ward off detonation which is understood.
Question is: if I stay with Motorcraft plugs what numbers or letters in a plug ID tells one about hotter or cooler

i'm not sure on that, but absolutely run copper ones.

Thx Expo
But why copper?

If you get nitrous Spindle, go all out and get some Iridiums. They aren't cheap, but I get absolutely no detonation now. Before with the copper ones when I hit about 9 PSI, I could hear/smell it. They aren't cheap, but very good insurance to have.

Who makes the Iridiums?
one of my main problems at this point is trying to cross refferance a colder plug to the OEM motercraft plug,i have all the NGK cross referance tables and there tech support says to use an NGK TR6 or a BR7EF if I slightly advance the timeing, am very :confused: on the plug issue.

NGK and Denso both make Iridiums that fit the heads. The NGK's are a bit cheaper, so you know I got those.

i'm thinking that i'm gonna change my plugs and wires this weekend,

i'm gonna pull the autolites and put in NGK G-power's and then some wires probably from carquest

I had NGK Iridiums in my '95 and Nology SilverStones in my '99

yeah I have the NGK Iridiums, and it did have great response

i put bosch platinums and bosch wires. the original plugs and wires were in the x for 105,000 miles. runs a million times better now

Just did Bosch Platinum and Bosch Premium wires. Cured my shudder on inclines and even throttle. Course the champion plugs and motorcraft wires had been in there for quite some time.

Autolite Platinums here. they run good enough for me..mainly ride from home to work and back. just street riding no off road.

I bought the Bosch Platinum+4s for the Explorer when I first changed the plugs, then switched to the regular platinums and didn't notice a bit of difference. The STi is still running on the stock iridium plugs. (I should hope so, it's only got 7,500 miles on it.)

Poll closed. You can still post in the thread.
