Issue with the Parts Girl

[The Deuce]

That's bad man. The way I figure it, about half the people in any given parts store know what they are doing. This is the same for most work environments. When I worked at Home Depot, guys who came in looking for something specific didn't get sold anything else. That was pretty much the rule. People who just described what they wanted always got sold up. I think that was a pretty good rule.

I do have a question about the plugs. I have never noticed a power gain in the beginning from better plugs. Is this just because my cars lag? Or is the advantage of better plugs, longer plug life?
