200 L6 Spark Plug Torque?

Pretty much standard is:

flat seat with crush washer = 25lbs/ft
tapered seat no washer = 15lbs/ft

Crush washers are supposed to only be used once. You can still buy them seperate at good old fashioned autoparts stores.
just a touch of antisieze goes a long way to making them come back out nice and easy, and is a requirement when installing plugs into an aluminum head. Be very stingy with the antisieze though as it is insulative.

Very good question! I've seen a lot of people who over tighten spark plugs, oil filters and oil drain plugs.

Not sure what the torque should be, but I have always just snugged them down with the ratchet. They don't need to be too tight.
