What spark plugs do you use?

[OJ1988]

I've always ran ac delcos in my chevy's, but lately, the quality seems to have gone down. I went through about 2 dozen off the shelf, many had badly bent electrodes, some were cocked to the side a lot, some were nearly smashed closed. All were oily and the porclien stained. Some almost looked used.

So, I am thinking of switching brands, and am cuirous what others use.

It seems like one of those topics like oil. No one has a good reason why they run one over the other often. It's usually a brand loyalty that is often pasted down.
