I'm running OEM part Bosh plugs I got on line as a part of the package with coil packs.
Leading evidence: 'Run oem part bosh plugs i got' (no explicit attributable resolution; this is a reported action or suggestion).

I did coil packs, plugs and tubes a couple of weeks ago in my '99 C2 and used these:

About to replace plugs and coils on an 02 C4S, wondering what plugs are recommended by the masses.

You will most likely change your spark plugs like maybe once?
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I'm running OEM part Bosh plugs I got on line as a part of the package with coil packs. My buddy got NGK plugs. Both of our cars are running well. If anything, I'd make sure you get the larger 997 coil packs for your car which are compatible with our 996 now too.
For Porsche/BMW ignition components, I try to stick with the three 'B's. Beru, Bosch & Bremi.
I did coil packs, plugs and tubes a couple of weeks ago in my '99 C2 and used these:
I like to use multi tip electrodes with Iridium plating, they last longer, I haven't tried to see what brand lasts longest.
But I always notice improvement with new plugs.
I do not understand why this is even a question. You will most likely change your spark plugs like maybe once? It is not like something you do every six months. Get some 4 prong Bosch spark plugs and new updated coil packs, change them all and drive another 100K miles.

Well Joe... Because maybe someone had a negative experience with one or another and it would prevent another from having the same experience. Happy New Year.
Happy New Year. And hence my recommendation. I bought some center tip iridium plugs and one of the tips melted. Went back to Bosch 4 prong OE plugs and have never looked back. Changed out my coils for the updated 997 coils at the same time. What led me there was a fairly persistent code related to a misfire (I forget which cylinder). Figured it was either a spark plug or coil.
Well, what I figured was it may have been due to several cracked coils, a flaw in the spark plug, manufacturing defect. Yes, that plug looks horrible. I was horrified when I pulled it out, but the other plugs looked okay. I don't really remember the mileage. I think I got less than 7,000 miles on those plugs at around 115K-120K miles. And remember, I have a 99 C2 with 146,6xx miles on my car now. Been through a lot. The car has run so much smoother and better with the Bosch plugs and new coil packs.
Beru is also OE. My car had the original Bosch FGR 6 KQC plugs that were installed at the factory back in 1999. They looked fine at 40,000 miles but I was doing coil packs and tubes so it seemed silly not to also do plugs since I was already in that deep.
I went with Beru because it seems like they've been slower to move manufacturing to China than Bosch has. Having said that, the last Bosch plugs I bought were for a BMW and made in Germany. The Berus were made in France.
