I finished up this how-to guide today. I'm coming up on another plug change, so I figured I'd throw this together while I was researching spark plug part numbers.
Replacing Spark Plugs on a 2ZZGE Engine (Elise, Exige, Celica, Matrix, Vibe, Corolla) | HowTune.com
In my research I found some interesting info regarding the use of anti-seize. I see random people recommending the use of anti-seize on spark plugs on forums, so I wanted to see how important it was (I didn't use it last time I changed the plugs on my Elise).
As it turns out NGK says not to use it as modern plugs that use a plating on the threads specifically for aluminum heads (spark plugs with shiny threads).
Apparently if you use anti-seize on this coating, the torque readings are unreliable.
