Hey...thanks for putting this together. We lost our DIY when some of our previous members left the forum.

If you don't mind, I'll make a few changes and post it in the sticky.

If you look at the pictures, he had Loctite BRAND anti-seize. Not Loctite RED or BLUE.

Weren't the torque specs amended to 21ft*lbs after people had problems with spark plugs backing out of the head and destroying coils?
Yep you are correct. I should have stated not to use any kind of thread locker. Loctite or any brand. Sometimes the name Loctite gets associated with only the threadlockers, not just a brand name.

The torque spec is 18ft/ibs. So wait for the pop and then your done with that.
I know my torque wrench works. I've tried 1 other that works also. However, I just put in new plugs, and being an aluminum head, I don't want to put too much pressure... but my wrench just doesn't want to 'pop' when doing the plugs, but it feels like I've put more than 18ft/lbs... but they just keep turning.

I'm just super worried about over-torquing them, or that the previous owner (or their mechanic) may have already done so on a previous set of plugs....

Thoughts? Should I just get one of the cheapie 'needle on dial' type torque wrenches?

Question, if I need replacement coil packs, can I only get them through Honda?

^No. I have seen them used (in great condition) in the for sale section. I picked mine up locally from a shop (again in great but used condition). Check in your local forum, you might be surprised what people have lying around.
