Servicing questions

I always use copper-eze anti-seize
The key to not over-torquing them is use a torque wrench.

NGK specifically says not to use anti-seize on their plugs, generally not necessary on plugs that have a shiny metal coating on the threads. Anti-seize can lead to over-torquing them. I didn't use anti seize. I did use a torque wrench.

Nice link. Good to read fact rather than opinion
Ive always used NGK plugs, fitted goodness knows how many hundreds over the last 25 years, never used anti seize, never broken or damaged a plug.

My service manual says to apply molybdenum based anti-freeze to spark plugs....With such low torque to them and if you are regularly checking them for gap and colour then they should never sieze.I torque mine to 11-13ft/lbs.

Most gaps get bigger by themselves over time.

i always use a SMALL amount of anti seize when changing plugs. crazy no too. just dont get carried away torqing them up
