IMSB Concerns
Hi, I have a MY2005 997 Carrera 3.6L
It is an early 2005 build, so it has the M96 engine.
I purchased the car in 2015 with only 6000 Miles on the odometer, and at present it has around 12000 Miles.
I have never seen any sort of debris in either the oil pan or the filter,
Would it be wise to get the retrofit done proactively? Or has the IMS issue been overhyped to the point where people are doing it just because they are scared?

Even if you address the IMSB with some aftermarket solution the solution may not last as as long as you would hope or the engine could suffer from some other serious internal engine problem that could result in the engine being as dead and worthless as if the IMSB failed.
If you are feeling lucky continue the way you have. Change the oil/filter regularly and don't run the oil too long. 5K miles or every year is good.
Be sure you run an approved oil and one with right viscosity for where you live/drive. For instance if you live/drive where it gets real cold: -25C or colder; Porsche calls for 0w-40 oil to be used to ensure proper lubrication at cold starts.
If the fear of an IMSB failure keeps you awake at nights or causes you to fear the car and not drive it research the IMSB solutions and pick one you feel offers you the best chance to continue to drive the car with no real worries about the IMSB.

Selling a model with the iMSB issue or not buying a model with the IMSB is certainly a solution to the IMSB "problem".
It is my opinion, and has been for some time, that a car with an engine that if I felt needed such a drastic preventative measures done to the engine would not be on my short list of cars I'd own.
Regarding the previous paragraph I note that in 2009 I was not concerned enough about the IMSB issue that I bought a new 2008 Cayman S. Unfortunately due to an accident (not my fault) shortly after I bought the car I never got a chance to see how the car fared over the miles. Still knowing what I know today but were I back in early 2009 I'd still buy the car. I just would not have driven it that fateful night Friday night.

A percentage of them fail. Enough to cause many people to seek retrofit / aftermarket solutions. Run the numbers and make the decision like you would an insurance policy. The cost of the retrofit (I'd personally recommend the IMS Solution if you go that route) vs. the cost of what happens replacing your engine if it fails. If you can't stomach either cost, this car isn't for you... because even if it never fails there will be expensive parts/repairs at some point.

Sounds like a garage queen, until you bought it, at least.
