Spark plugs?

[slck6t9]

Hey guys, just wondering what the consensus is on what brand of spark plugs to use?

Thanks

What engine, if its GM I prefer the AC Delcos, Fords Motorcraft, Chryslers well AC or Motorcraft will work in most any engine.
I like ACs as they will show blistering before any other plug and have several types.
Denso Iridiums are good also.
More info on engine and typical use.

fyi... autolite is motocraft. Just different printing. They also make some AC plugs since Delphi shut GM down years back.

I use AC. They work fine and I dont really buy into the whole fancy spark plug market.

I like Autolites, never had any life out of the fancy $$ plugs.

In my old 327 which had typical go-fast parts and cam, I had my best luck with the Autolites, next was Champion.

For some reason, I could never get the AC Delco's to last as long in that motor.

Thanks for the suggestion's. As for the motor, it will be my 383 stroker that's driven every weekend. I currently use AC Delco but was wondering if there was better.

Thanks

We dyno a lot of unleaded SB and BB Chevy engines and Pro Stock GM engines on racing fuel and the Autolite plugs have been flawless.

NGK's work well for me. (Bosch if it's a german car)

FYI AUTOLITES ARE JUNK, RAN THEM THEN WE PUT CAR BACK WITH STOCK MOTORCRAFT.
Strange missfire went away and quiit throwing codes.
I have yet to have good luck with any Autolites.
