Pulled these plugs out after a month...not sure if these are good or bad...

Looks light gray to me, which is fine. Light gray or light tan is what you want to see.

Thank you! I wasn't sure what to look for.

Shout out to Vulcan Verses for the hi-tension wire info.Thank you!
Dennis Kirk delivered today and it took me one hour to replace all four wires, excited for tomorrow's ride.

You're welcome, the link above is a guide for reading plugs. If you pull enough plugs you'll eventually see them all. Except the ones related to lead, since we don't use lead now.

A dab of anti-seize on the spark plug threads is a good idea also.

Yes! Always add just a dab of anti-seize on the threads...dissimilar metals tend to fuse together when corrosion sets in.

Marketing. Their plugs are so good you never need anti-seize.

Bet they're not interested in replacing a head if the plug seizes.
As far as lube or sealer changing torque readings, if that's really a problem, I've never run into it. Some applications require one or the other on the bolt threads.

As far as using a torque wrench on spark plugs, I've only done this once. Just to humor the owner.

My gut tells me that there’s a grain of truth to what they’re saying but at the same time it’s probably an extremely rare occurrence. Which to your point is good enough for marketing. Reading this thread the other day reminded me I wanted to get new plugs and found that link during my search. One of the many small projects I have lined up for the coming months.

Mine look EXACTLY the same after driving for also ~one month using new plugs.

Nineteen years working at a honda dealer, ive always added a small dab of anti-seize on every sparkplug i've replaced and never had any issues...but that was six years ago

my '92 runs on a single vm38 mikuni by the way, because i'm too cheap to replace the stock (recycler special -green paint on the bolts) carbs.

Did some time with a Honda dealer myself, every once in a while there was a dry plug hole needing a helicoil.
