Cannot locate 958 V8 Spark Plug change tutorial or at least list of to

[958S]

I have a 2012 Cayenne S and I have looked high and low and cannot find a tutorial on changing the plugs on the 958 V8, only the 955. I have changed plugs on many vehicles before so it is not the basics but rather the unknown tools that may be required or tricks to getting a difficult plug out.

Thanks in advance.

Also the torque specs for the plugs (dry since it looks like all Porsche are without ant seize now), is it 22 ft lbs like the 955?

Yes, spark plugs are 22 ftlb.

and ignition coils are 7.5 ftlb.

Thanks. I think I figured out all the tools I need as well, just need to find out what the gap should be set at. I am thinking they may be pre gaped but I always check and double check. If anyone knows please let me know. I will try to post a summary when I am done listing all tools and specs.

[958S]

Surely some else has changed their plugs and checked the gap. I have never blindly thrown plugs in.

[958S]

Looks like maybe the 4 prong plugs to not get changed and are set from factory.

[Loren]

I maybe OCD but I always check them - you never know when some handler has dropped one.

Hence I look for cracks too.

[958S]

I check to, and the box has the correct gap printed on it so that confirmed my thought. Thanks

I like to change my own basic maintenance as well. I located this link which was helpful

the angle bit driver can be bought at Lowxx for a few $ less than Amazxx

 

the magnetic long reach spark plug kit can be ordered at Lowxx as special order or also available on Amazxx as "GearWrench Tools 41740 3-Piece 5/8-Inch Magnetic Universal Spark Plug Service Kit" for a few $ less

 

i dont have any instructions either, but i guess it's just removing the covers, accessing the coil packs, removing the connectors to the plugs. 

 

as mentioned above torque to 22lbs but i'll just feel for the 'crush washer' being crushed.
