Just a question about spark plugs:
I got some Denso 5345 iridium plugs (one option as listed at different sites) for 09 997.2. c2.
Any pros/cons from the experienced about plugs?
these are single electrode/ground type.
I am not planning to do them for a little bit, just setting the stage.


Thanks all!

There is a reason I believe why the factory plugs have multi-ground electrodes. I would be very reluctant to experiment with single ground electrode plugs.

I do know at least in one case the Porsche owner found the replacement plugs although listed on the reference chart as interchangeable with the factory plugs proved not to be. The engine ran poorly and only after the owner removed the new plugs and installed factory plugs did the engine run properly again.

My point of view is why add to the drama of what should be a wham bam thank you ma'am service and throw unknown plugs into the mix?

When it comes time to have the plugs done for either of my cars I just have the tech install whatever the factory calls for and then go on about my business until the next 60K miles (or less for the Turbo) rolls around and it is time for plugs again. Between plug services I give them about as much thought as I do about the newest kitten video on YouTube.

Point (s) well taken. Most likely I will get the Bosch original 4 electrode type.
thanks!
p.s.: have you seen the video of 14 kittens scaring a gorilla?

Porsche uses copper electrode plugs because they transmit the highest amount of energy with minimal losses, the compromise being the electrode erodes quicker than the iridium.
