After having changed the drive belt yesterday, next job was the spark plugs.
Access is very limited so anyone with large hands might struggle.
Again, I viewed a few videos on youtube first.
I removed the wheel arch front section liner just to improve access to the front plug.
I was expecting to see an aluminium heat shield between the cat and the coil packs as per videos seen but mine didn't have one (have only done drivers side today).
Only fiddly bit I found was removing the coil pack connectors but I used one long screwdriver to release the connector catch and another to push the connector away from the coil pack.
Old plugs came out very easily (were last changed 4 years by Porsche Centre).
Rear plug is straight access with a few socket extensions, front two need a short extension down the spark plug tube, a UJ, then another long extension.
Middle plug has the most restricted access of all three, I had to put the spark plug socket and short extension down the spark plug tube first, then fit the UJ, then the long extension.
I fitted the new plugs by hand until they sat on the seal washers using socket/short extension.
Plug torque setting is supposed to be 28 Nm (21 ft lbs) but you can't use a torque wrench through a UJ as this will affect the point at which it clicks.
The only plug you could use a toque wrench is the rear plug as it has straight access using two extensions.
So rule of thumb, seat plug by hand then tighten up to 90 deg.
Did this on all three and checked the rear plug with my torque wrench and it clicked at 28 Nm with no further tightening so probably 90 deg from hand tight is ample.
Will put up a few pics.
The plugs I used where Bosch FGR5NQE04.
I had these from when I had my 2.9 987 gen II Boxster but never got round to fitting them.
I spoke to my local indy a few weeks ago about getting the car serviced soon as it is due a major and I mentioned I was going to do the plugs myself with the plugs I had for the 987.
But I was informed that the plugs are different for the 987 and the 981, different reach he said.
I said that my internet research revealed that they use the same plugs.
But no, I was told they are different.
Not so, the plugs I removed are the same as the ones I had for the 987.
Was going to do the passenger side tomorrow but on refitting the wheel my locking wheel nut key failed so have had to order a replacement from Porsche which is arriving on Thursday hopefully.
