Spark plug advice

[efiste2]

I took the plugs out of my 20k 07 ford focus this afternoon as i wanted to check they could be removed correctly, as there is a known problem of the bonnet mounted washer jets leaking or not sealing properly in the hole in the bonnet, so that water can drip into the spark plug holes in the cylinder head, and therefore rust/corrode the plugs in place. Mine all came out fine but were very "Dry" for want of a better word. SO MY QUESTION IS, What sort of grease/lube would you more experienced chaps put on the threads of a spark plug to prevent them seizing in the threads, Perhaps a smear of coppaslip....

Been using copperslip for years on spark plugs and found it magic. Stops any seizing up/braking of plugs

Also remove them when the engine is hot.

Never attemp to remove spark plugs from a hot engine.

That is only in case you burn yourself, they still come out easier when hot.

So can the aluminium from the thread if you're not lucky.

They look normal, don't they, they're certainly not coked. maybe check the gap distance, or failing that buy some new bosch plugs which will be pre lubed?
