You can, if you prefer, I would just shove a rag down the chamber with a grease cutting agent. You just need to clean the top of the plug.

Dielectric is the grease I'm referring to at the bottom of page one. Infact, that's the ONLY grease I'm referring to.

I lay a bunch of rags around everything before I pull the rail. Also when reinstalling, there's always a little gas the works it's way in there when stationary. You wrap rags around that as well, -yea keep ip it dry as you can.

Yea, I know Matt doesn't say much about greasing, that's why I wondered if anyone else has done a write-up lol.

You can buy a full set of OEM quality cops on Ebay for around 80 bucks - look for listings from Global Automotive or Uneek Supply. What you want are DG508's.

Almost forgot, not sure if it's been mentioned yet, - DON'T use Anti seize on the plugs. If you do, you have to reduce torque by 30-40 %. If their over torqued right now, lord have mercy lol.

It's allot safer not to use, you don't need it. If you torqued them dry, your perfect

Since their set at 20, you should probably be okay. Not sure, but glc knows the max torque on those and I believe your in safe territory. Max is listed here somewhere -

http://www.blownoutsparkplug.com/

Personally I don't use a torque ratchet on those, I just go 1/4 - 1/2 turn after snug or after their run down. I believe it says this on the box, well it does on mine, I use Denso's tho.

If you antiseized them, torque them to 30. The heads are safe to 100.
