Spark Plugs?

[Forzfed]

I'm currently running some Delco 43's while I break in the 4.1 but I would like to change plugs.  Thinking of autolite.  What do you guys think or run?

I like the Autolite R23s  or the ngks

I've been done with Delcos for a few years now. They aren't the blue chip standard anymore (much like the oil filters).

NGKs for me all the way.   With my experience with motorcycles and my racebikes, I'm amazed I didn't make the change eons ago.

I use Autolite 23's gapped to 0.035".  This is also with a hot wired CCCI.  Good so far to 23 psig and methanol.

For most applications any brand will do. The problem is all brands are counterfeited also. Don't by from ebay, amazon, walmart. Go to a real auto parts store and pay the price. Cheaper in the long run.

Agreed. I go right to the dealer to buy mine.

Are there some out there who can actually tell the difference in the plugs? NGK? I've never heard of them. I'm thinking I want to change out plugs soon since the new install of the kit.

I’ll be damned if I’m going to pay nearly $3 a plug at some chain parts store, when I can get them from rock auto for nearly half the price.

NGK are Japanese plugs and they seem to be consistently better built.  Everything else seems to come from China these days

I would say that the more boost you run, the more likely you are to see a difference in plugs.  I find that NGK and Autolite racing plugs (AR23) are consistently better than the AC's these day.

Yes - but I order 40 or more at a time. They are cheap and don't go bad sitting in a box on the shelf. As long as you don't forget you have them!


Brad put some 42s in that thing and put the screws to it!

[Steve Wood]

I would have to be reincarnated to ever use 40 plugs LOL

Most people don’t look at them. On the bottle I was always putting in fresh, making a hit and checking them. It’s good when the data and plugs are telling you the same thing. I’ll probably be reading them on the turbo setup too.
