Hey guys, I read about a new spark plug called the G3 Dimond Fire
Im needing new spark plugs, could you recoumend a good 1?
I drive a 1995 f-150

 

motorcraft copper resistor plugs

 

thanks for the advice

 

Another vote for motorcraft. They've never let me down. I like to let the latest and greatest get proven by time and other peoples experience before I buy them. Just my 2 cents.

 

How are Autolite Platinums? Vs the Copper ones? I heard the copper ones wear out faster.

 

AC Delco is what I've always used

Should I get the regular autolites or the platinums? Just wondering which is better for fuel economy and performance/reliability.

 

I use autolite copper cores. You only need the platinum ones if your engine eats spark plugs. I had a chevy with a 305 that had worn piston rings and the plugs got gummed up pretty often. Copper cores will work just fine.

 

The platinums last longer, that's about the only difference.

 

copper is a better conductor of electricity then platinum. sure copper needs replaced more often but honestly it just keeps you up on proper maintenenance intervals

 

Just look under your hood at the sticker, take that information to your auto parts store and buy a set of Motorcraft resistor plugs.

People talk about what is a better conductor of electricity but if you are using resistor plugs what difference does it make. I will take steel, I think they last longer and are less expensive.

I always test the new plugs before I put them in and throw away about two new plugs out of every eight in a pack anyway.

Most plugs will fail at about 125 psi on the tester anyway but I pitch the ones that quit below 110 psi.

I do not believe in all the sales hype that you hear about fancy plugs.

 

i gave a friend with a 1931 Ford model A a set of nos spark plugs for christmas and they look amazingly like the plugs i put in my 4.9 engine.

 

I'm not advocating platinum plugs by any means, but usually it is just the electrode tips that are platinum coated. The whole plug is certainly not made of platinum, so I don't see where there is much difference from a conductivity standpoint. I buy the regular ol' cheap plugs for my truck too.

 

I am running autolite platnium and had no problems for the last year or so. I would recomend either those or oe motorcraft. Mine had Champion in it when I bought it and it had no power and got horrible milage now it runs great and gets not so horrible milage.

 

NGK V-power plugs, Autolite copper, or Motorcraft copper is the only plugs I will use in my truck. Anything plug with the word Platinum in it is garbage in my book...
