Plannin' on changing the spark plugs on my 2011 Panamera S.
999-170-130-90

Any good alternatives from Bosch? Heard some.

Should I opt for copper or platinium?

If so from Bosch or either, please provide the code for the spark plug. Thank you.

Stay original , what is the gain from not ?

Go with original replacements, that is the correct part number. There is NOTHING to gain by going with a different choice if this is a regular driving car.

No no, I heard that even the Porsche Dealers use this Bosch Sparkplug part in their cars by default, but just with a Porsche logo on it. Looked it up and saw multiple people saying that, so I wanted to check on this forum first. Basically, the Bosch part with a Porsche logo on it is used by dealers.

Just wanted to confirm this information and see from here.

Bosche makes the Porsche plug, they have an equivalent plug seen above my post. That is the only suitable plug if you do not want to buy from Porsche, in my opinion.
