Just changed mine.

Found that plug no3 had worked itself loose.

When I put the new ones in I couldn't find a recommended torque setting so I nipped them up and then gave them another 60 degrees (because it felt 'right').

Is there a 'correct' torque setting?

25Nm

25nm, then go over all 6 again.

Car is all back together now. I have no intention of removing the inlet manifold, cable tray and coil packs again just to check the torque settings 

I am fairly confident that they are all tighter than 25Nm but I might go and play with a torque wrench (on the bench) just to reassure myself.

Never personally torqued spark plugs on any car - as you say tighten sensibly and all will be well - down to experience I guess

[chrisgixer]

As master said a while back, the washers on the plugs can relax after torquing. It's there for worth a re torque to make sure they are settled. Before it's put back together.

If you change them regularly, they don't get time to work loose

Also no need to remove the inlet unless you're needing to get to the oil cooler/thermostat/coolant bridge

And having had to helicoil spark plug holes on three Omegas now for others after people thought they know how tight they need to be....I would recommend a torque wrench everytime (as it takes no extra time and means its done right everytime  )

Providing of course they know how to use one. Experience should also tell you to stop If the wrench has failed . . .which isn't unheard of
