I have a couple older above plugs, stock #3526-they have a gold/zink like plated body-it looks like the ones I saw on line are more silver
Are they just the same thing, just updated or something
I have been running 6's, with more boost I wanted to run these

I've seen the same when I buy them. I'll get mixed stock.
My guess is they updated the coating.

Same plug, different coating
Just a non projected tip heat range 7 plug
I've used them for a while with good luck
