DIY 991 GT3 spark plug change

Regarding the plugs: Are you guys concerned about using the non-Porsche branded version of the plug? I know technically it's the same plug, I am thinking more about warranty, CPO etc. Price difference here in EU between branded and non-branded is quite big... ($27/pcs vs $50/pcs)

I used the Porsche part number (ending in 91) for my 4.0

Yes, I have both part no:s (for 4.0):
OEM: 999 170 153 91
Bosch: ZGR 5 NQE 04
which should/must be the same plug. My question was if, in a warranty/CPO situation, a dealer would point to a non-Porsche branded plug for a reason not to take responsibility (for whatever may happen).

When searching Bosch site, there is no recommendation for the 2018+ GT3 4.0L, just the 2014-2016 GT3 3.8L.

Without further info, I am much more comfortable buying the "91" Porsche plugs...

Ah, you are probably right. At least on the shopping site I am looking, both Porsche numbers are listed as OEM numbers under the same Bosch product... Hmmm.

According to Suncoast a 16 RS uses the earlier 90 plug:

Grant, it seems I can't see the recommended plug on the Bosch site you're referring to above. It shows all the plugs... And yes, the 4.0l engine has no recommended plug at all. Is there another (official) way to cross reference Bosch part no to <porsche OEM part no?

I couldn’t find a satisfactory answer, so I just decided to go with the Porsche plugs.

Changed the spark plugs on my .2 GT3 yesterday and wanted to thank everyone that has contributed to this thread. Reading through all the posts gave me the confidence that even I, being an average DIY mechanic, could do it. ;-)
As others have stated, it's actually fairly easy as long as one has the right tools as listed in the beginning of this thread. I removed the wheels for easier access. Took the opportunity to clean the BMC filters too.
Like somebody had posted, undoing the 10mm bolt holding the Bilstein sensor and pushing it out of the way a little made access to number 3 cylinder plug (front left) so much easier.
My car has about 6K miles so it was the two year interval that prompted the change. All six plugs looked about the same, not sure if they looked good or bad since I have no experience changing them. Maybe someone that know can chime in? Sorry, picture a little blurry,
Took the car out for a drive today and it feels like the engine is running smoother and stronger. I have no scientific proof of this just the way it feels.
Thanks again to you all for helping me save on labor cost plus letting me forget about this darn virus for a couple of hours!
Stay safe.
