Hello -

I have a MY04 CTT and plan to replace the plugs and coils. I know there have been many noted issues with the early coils that came on these cars.

I am thinking the MY10 CTTS coils are most likely updated even further. Has anyone tried this? Anyone see any issues in trying this?

I have noticed the the 996 911 guys upgrade to the 997 coils and note power gains with no software changes required just better spark.

Please let me know your thoughts...

A good Porsche parts guy (and some are definitely NOT) could answer your question in a split second.

Luke or Bob at Sunset Porsche in Portland, OR are my go to guys.

I'd google 'em and give 'em a call.
