That's funny, I got a set of those too and they were in the garbage 2 days later. They were leaking spark all over the place. Probably the worse set of wires I ever dealt with, and they were brand new. They had that silicone slime **** in the boots. Don't know if I just got a bad batch or what.
My mechanic yanked them out and put a better quality set in, they are great, just don't know what make they are...
I have autolite plugs in mine right now, it's running fine so far. I prefer Delco parts when the budget allows.
Also run NGK in my boat and ATV motors no problem. Standard also makes some good ignition parts.
