I have more than 25,000 on my current set, but run considerably more compression and heat than a stock 996.

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.

In the Porsche NA engines, you will see no difference at all, so the choice is yours.
Here's the part number: 999 170 207 91
You need 6 of them. However, $14.32 is RETAIL, you can do much better by going through some of the more common vendors we use around here.
For example, Suncoast sells the ENTIRE kit (6 plugs) for $50.

NGK, Beru both great plugs. Get the one recommended for your specific year. Try a Porsche parts dealer rather than a generic spark plug dealer.
There are Porsche dealers like the one listed above that will give better prices. Or try Pelicanparts.com for plugs, they have the part numbers in their catalog for each year.
I would also add that you should not use Denso Iridium plugs as I have heard of multiple incidences of the electrode breaking off into cylinders and trashing motors.
Riad - your wit and humor is always hilarious, if the studio doesnt work out, I see another career path...................ok, back to the subject of putting over-priced crappy plugs in our cars
I am going to have to go with '99 on this one, I will try the NGK's next
Ha! I'd love to see the look on my wife's face when I tell her I'm quitting it all and hitting the road as a stand up.
On a serious note, why would anyone choose a plug other than OEM? Is there an expectation of better performance?
And WTF is up with that snake looking split fork plug?
Copper, by far, is the best thermal conductor available and their tip design transfers more heat away than others. They also cost $30 for all six plugs, so why not?
The type of spark plug will not change your performance one bit. Your engine produces more than enough spark, so platinum or iridium plugs are not neccessary and are simply a waste of money. Their only advantage is they can make up for a weak ignition system and they last a little longer than a copper plug.
HOWEVER, platinum and iridium plugs do not transfer heat as well as does a copper plug for 2 reasons. 1) copper is the best thermal conductor and 2) the wider design of the electrode allows more heat to get to the copper to be transferred to the block. If you are running on poor gas, copper is safer.
In the Porsche NA engines, you will see no difference at all, so the choice is yours. If you are running boost or NOS, NEVER use platinum or other narrow tipped plug.

How many miles would you think these GGK plugs should be good for? My 1999 996 is my DD and I'll reverve my 964 for the track, so no track time on 996.
Also, can these plugs be gotten at Advance and the like? Do you have a part number for our cars?
Thanks for the lesson!
I get the plugs at a local auto store....never looked at Advance for them. Part number is NGK BKR6EK. As far a how long they last, I would guess 50,000+ easily on daily driver. I have more than 25,000 on my current set, but run considerably more compression and heat than a stock 996.
