So I'm planning to replace my spark plugs, and I am debating if I should apply anti-sieze to the threads or not. I've read that anti-sieze should not be applied to spark plugs coated with a copper (or nickel, can't remember) coating. The plugs I have are the plugs that come with the 850 tune-up kit from FCP Groton (Volvo brand plugs).

So would these plugs require anti-seize or not?

Thanks

 

Yes use it.

That is a bull ****.

Anti-seize compound should be used on aluminium-head engines. For steel-head engines, a drop of engine oil is recommended.

Make sure not to get the stuff on the electrodes. Apply only to the top (closer to the wire end) few threads; that's all you need.

To seat the plugs correctly, either follow the torque value in the service manual or hand-tighten with an extension until it stops, then give it 1/4 turn with a ratchet handle (for gasket-type plugs only. Non-gasket plugs require only 1/8 of a turn).

Definitely use it!

 

Thanks guys. Anti-seize it is then.

 

No problem
