Should anti-seize be applied on spark plug threads before installation? Anti-seize is generally unnecessary for modern spark plugs with coated threads, as it can affect torque and lead to over-tightening. Always follow manufacturer recommendations; if anti-seize is allowed, apply it sparingly and away from the firing end, reducing torque by about 10-20% to prevent damage.
