Not absolutely necessary, but often recommended to prevent the plugs seizing (getting stuck) or possibly breaking off during removal.

Personally I don't use it. Don't torque them down..they don't hold the head on. and Don't use too much or else the plugs won't make a good ground and you will get misfires.

It's not a matter of using anti-seize or not. It's which anti-seize do you use.

Answer: Copper



Permatex® Copper Anti-Seize Lubricant

A premium quality copper anti-seize and thread lubricant that may be used to prevent seizing, corrosion and galling where high temperature conditions exist. Contains a high percentage of micro-fine copper flakes in a semi-synthetic grease carrier and is fortified with high quality rust and corrosion inhibitors. Temperature range: -30°F to 1800°F (-34°C to 982°C). Provides good electrical conductivity. Meets Mil Spec #907E.

Suggested Applications: Spark plug threads installed in aluminum, exhaust manifold bolts, engine bolts, oxygen sensors, knock sensors, thermostat housing bolts, fuel filter fittings, and battery cable connections
But I've used the regular stuff(aluminum + copper) for many years on spark plug threads in aluminum heads and never had any issues. So I'll use either, but preferably the copper.
