I prefer NGK U-groove plugs myself. I would like to try the new Denso iridium tip ones but they do not make one for older motors to my knowledge yet. -Jabin

Every engine, blown, or N/A, I've been around had NGK's in them, unless the car was sponsored by someone else.

I can't believe out of 40+ views only two people know what kind of plugs they run.... :doh:

I've always been an AC Delco guy because if you do your homework, you'll know what temp range you need and A/C offers them all generally but an engine builder I used to work for swore by NGK's. Being friends with the who's who of auto nastalgia and at 70 years old, he'd know better than me! :D So, that's what I use on the special cars.

Autolites have been good to me lately. Cheap and the Advanced carries all the different heat ranges. AC delcos otherwise. Unless its a ford then Motorcraft. Champions only go in my lawn equipment

Bosch Platinum for NA engines. Cheap ($2 each), small diameter electrode (can run slightly wider gap), and last long.
