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.

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'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.
