Re: spark plugs
i like Autolite 25 or NGK plugs. Stay away from platinum plugs in older motors

Re: spark plugs
AC Delco - if it's good enough for the GM factory, then it's good enough for me.

Re: spark plugs
use AC Delco plugs in a GM. Autolite plugs in everything else. Use Champion plugs ONLY if you can't get anything else, and it has a mower deck under it.

Re: spark plugs
This is just IMO but I use AC Delco plugs most of the time. Autolites have treated me very well in all my race applications also. Even better than AC Delco
I would not tell my worst enemy to run a champion in his lawnmower  JUST MY OPINION THOUGH RJ22...

Re: spark plugs
Just curious cooters, why not the Platinum plugs? I've been saving pennies to spend $8-$12 a plug, I have headers & I don't want to change them very often, so I thought I'd get the spendy ones.

I'm currently trying to get a newly-swapped-in 350 to start, and during the swap process, I put in some Bosch Platinums (and stupidly threw the old nasty ones away). Now it won't start. With a screwdriver in the plug wire laying near a ground, the HEI will throw a 3/8" spark. With a plug sitting on a ground, it SOMETIMES makes a spark, but even then it seems weak. Either way, I've been through everything else, and I'm pretty sure it's the plugs giving me grief. Now I have to wait for the munchkin to wake up from her nap so I can run to the store... Anybody know WHY platinum plugs don't work?

Re: spark plugs
bosch dont work because they have no exposed electrode so when any carbon or fuel gets on the plug they misfire. Platinum plugs have a tiny electrode and also tend to misfire when oil, fuel or carbon get onto the plug. Platinum plugs work well in motors that run really clean with higher cylinder temps. These are my findings anyway.

Re: spark plugs
Use AC Delco, but if you need header space, then I have been running the plugs from Accel. I have been using them for years and they have not failed me yet.
