I need to replace the sparkplugs in my formula and wanted to ask what you guys recommend. My wires and distrubitor are all new (<1 year) so that should be ok. Thanks.

I stick with what the General ordered, AcDelco.

Bosch platinum plugs...foul out in a few hundred miles
Champion...weak ceramic insulators that break easily
Autolite....Ford plugs in a Chevy engine??? No way.
Splitfire....snake oil, no benefit or gains just lots of $$

AC-Delco plain resistor plugs..cheap and what the mfg recommends.

i use NGK coppers.. works fine for me, its cheaper and easier to get the ACdelcos for me..so i gues sif you can get those might as well.. but NGK coppers dont foul and so far have been great. (a year or so..)

Thank you all for answering. Looks like AC Delco for me.

:wink:

i should try those.. never have used em in my maro.

used ngk iridiums, champion copper, NGK plat, bosch +4, bosch plat..

i gotta do a spark plug change soon..when i save up enopugh $ :(

stupid school and the drain on my $$..

Anyone have an opinion on these? Kinda expensive but the write up review on them was good.

NOLOGY-SILVERSTONE SPARK PLUG - With Large Diameter Silver Center Electrode, Performance Non Supressor Design, 137% More Spark Power Increases Horsepower

never tried them..i would rather trust something that is proven, but if you want, you should try em, and then after a few months, try different plugs.see if you can feel a difference.

Gimmicks, all of them, other than the NGK, I've never ran 'em bu thave heard good things as a runner up to Ac's.
