What kinda sparkplugs everybody running in 5.0s

I moved your thread. It may generate more response in this forum. But, to answer your question, I run Autolites in mine. Never had any problems with them.

i run autolite 764s in my 85'

bigred90gt · 07-16-2003, 09:36 PM

I run NGK's in mine and my 93 F-150 and they are great. Never had any problems, even with the MSD.

GhettoPop · 07-16-2003, 09:37 PM

Bosch Platinum +4, don't know if people are big fans of this plug but I have had them in for 2 years and never had a problem

VeNuM · 07-17-2003, 09:06 AM

Platinum's may last longer, but for performance, definately go with a copper plug. ~Brian

Platinum plugs will spark more reliably but with a cooler spark. You can improve performance by going with a wider than stock gap. Platinum plugs do have a copper core, BTW. I use Autolite 3924s with a HI-6S ignition and MSD 8.5mm Superconductor wires. Non-platinum are the way to go if you change your plugs often as any good performance nut would.

I will be trying the new Denso Iridium plugs, advertised in MM&FF. But I run the autolites now with no problems, have for a while.

I was thinking of trying the DENSO plugs, too. I can't seem to find any place that sells them. I'll probably wind up buying them online.

I use Motorcraft AGSP-32c with MSD and 12lbs boost.

Motorcraft AGSP-32c here also. Had some problems with autolights once, try to avoid them somewhat now.
