If stock do .031 Gap, if tuned, .028 is a good starting point. They will come gapped.

I'm kind of curious why you would even do boots at 43k. Over the last 20 yrs I've only done wires if I upgraded the ignition, had some sort of external issue (water etc) or if they were super crappy wires. But most of my previous vehicles all had coils/boots as single units. Honestly haven't even looked at these yet.

read on some thread here about the recommendation on the boots /// sounded convincing enough for me -

I just received these exact ones from Rockauto.com on Wednesday. About $8 each. After installing them, I think it resolved an issue of occasional shudder while idling. I will give it another week of driving to determine for sure.

Yep! Advantage of getting them through ZFG, is they are gapped to exactly what they need to be. Little piece of mind. The gap is just as important as the plug itself.

What torque specs should spark plugs be?
