Thanks for any help.

Very easy, you just have to be CAREFUL to avoid cross-threading them with screwing them back in. The rubber spark plugs might be a bit of a mare to remove, you just gotta use quick force to pull them off. Also when you put new plugs in make sure to add some copper grease to the threads to make them easier to replace the next time

Cool thanks mate, shall I just hand tighten them or must I do it to a specific torque?

I'm sure there's a specific torque but I don't have a torque wrench so just make them hand tight. Maybe someone else will know.

Spark plugs changed now for some Denso iridium ones, thanks for the advice and if anyone else needs to do it, it is easy providing you have the rite tool. I can't believe how much some garages charge to change them after seeing how easy it was myself.

I changed them on my old very easy, but the spark plug socket i had wasnt very good and didn't grip the plug very well after it had unscrewed it!

Yeah Thats what I thought could happen, I was going to order a spark plug tool from ebay but decided against it and managed to borrow a high quality one form a local motorbike shop. I would like to buy my own high quality one eventually though.

hi mate. Can you explain "use quick force to pull them off". what exactly does this mean?
cheers.

Give them a quick yank rather than pulling on them gently, they should come off easy enough.

but could't they break in this way ? Mine were checked/replaced like 2 years ago by ford. I have no idea how/what they did so I'm afraid of what I might find .
My magnacor leads and denso iridium spark plugs are waiting to be fitted for a few month already. I was waiting for the GGR so I do all together. Now I'm waiting for oil catch can to arrive. I'm always waiting for something .
cheers.

You should be fine mate, they are made from pretty tuff material, it was the first time I had ever changed the plugs and its really easy

I tore two plug leads by pulling 'gently' rather than a quick tug as I should have, so yeah, pull quick and fast IMHO.
