6 plugs, 6 coils, engine filter, and cabin filter.

Those plugs aren’t even sharp they still have a couple hundred thousand miles on them.

Thoughts on putting anti-sieze or dielectric grease on the replacement plugs?

Afaik, that’s generally discouraged. You want a good seal and ground.

I remember doing plugs, rotors and cap every 50k, and wires every 100k.

Never, ever, ever put antiseize on a plug.

As a mechanic, what the hell are wires? /s

👍

I’m just about to attempt this job and two separate videos mentioned it, thanks for the confirmation

one of them is significantly cleaner than the others. is that cylinder working ok?

honestly no idea, ODB says everything is fine. Its a honda V6 and there was a class action around the Eco mode causing misfires, but my van is already 50k past that extended warranty.

Anti-seize no, dielectric grease yes.

guess it will be one of these things you just accept and move on

i mean, so far its been fine and I just keep up with all the normal maintenance not much else I can do.

High tension leads?

The reason I like working on diesels.

dielectric grease yes.

That’s also questionable. Rotax went through a ~5 year phase where they recommended dielectric grease on spark plug threads and applied it to newly built engines. After that, they did an abrupt 180 and issued Technical Service Bulletins saying not to reapply it when replacing spark plugs. And AFAIK, they stopped using it in new engines.

I use Rotax as an example because I trust their tech. They make some of the best engines in everything from aircraft to motorcycles.

Also I note your original plugs did not have dielectric applied.

correct, they did not, since I was swapping the coils this time around it was recommended to me so I added a pea sized dab to each coil before I installed them.

Yeah, honestly I never saw issues one way or another, but I assumed they had good reasoning.
