[928uk] 928 S2 service parts

Well apparently those WR7DC+ are the replacement for WR7DC; they have a different central electrode material. They're fine, but the box says their gap is 0.8 while the Porsche spec is 0.7 +1, so because plug gaps widen with use I would set the gaps to 0.7 with a metric feeler gauge and a proper spark plug gapping tool. Don't ever touch the central electrode, it's easy to damage it. A spark plug gapping tool allows you to carefully bend the outer "ground" electrode away from or towards the centre electrode. Now is someone going to tell me that re-gapping them is wrong because the new electrode material needs a larger gap?

Nothing wrong with having 2 spare spark plugs. Put them in your rear seats glove box alongside the spare bulbs, spare fuses, spare 141 951 253 B relay, and fuel pump relay jumper wire 😊 

Best regards,

Jonathan
