The Sparks
Youtube showed the coilpack and leads removed..
I just simplified that:
Undo the 3x bolts holding the coilpack..buys a little free space around plugs
I used tape to mark leads for cylinders 1 and 3 ( to save muddling leads..and having issues)
Pull plug lead #1 ( timing end)
Experiment with your tools here.. you want 'a straight line' from the plug up to 'space' where you can apply the necessary torque
Youtube talked of moving injector wiring.. I didnt need to
Wind out the plug... then carefully remove it
Swap plug.. carefully lowering it into the plug hole
TAKE CARE OF CROSS THREADING!
A tip..
when it has gone Tight.. back it out 6 turns.. if its still in the threads :good
If it has come loose: you were cross threaded
Carefully wind down into its threaded hole
NEW PLUGS.. have a deformable sealing washer.. so feel odd when applying their 1st torque
When torqued Refit the plug lead.. they have resistance from the rubber boot then 'ride over' the electrical contactRepat this procedure for the 3 remaining plugs.
I lined up all 4 Comparing their 'burn colours'

I asked around on here and there isnt much choice with plugs...
BUT.. general concensus = factory issue are poor
And Iridium plugs are recommended
HOWEVER.. there isnt a direct replacement..
I Fitted the Bosch Iridium in the pics
No obvious difference.. but they should be good for 30k..not the 12k of the basic plugs
