As far as the IPD plenum, I’m not sure if it will provide the same power gains as it did on prior models. As far as I know, it’s still not available. IPD says 2022 but you know how that goes. Also, I’m not sure I’d replace the plenum while under warranty.

Overall, it was fairly easy. The only hard part was taking apart the GT3 PDK shift knob because of tabs that are under a collar holding it together that are hard to reach. I can post the entire how-to on this site if requested.

Will the warranty cover the cost of a given repair?
The source of the problem was due to a defect in manufacture or design. ---> Yes, if still in the warranty period
or
The source of the problem was not due to a defect in manufacture or design. ---> No.

Of course, things are not always so black and white. Dealers, distributors (Porsche Cars NA is a distributor), and manufactures might put the blame on your driving, some modification you made, or service by an independent mechanic. They may say the problem is actually part of the normal design and function of the car. They may deny you warranty coverage but still pay all or part of the repair costs as a goodwill gesture. Maybe your driving broke something and they choose to overlook it and pay for the repair. Things can go either way.

So to address your comment directly, will modifying your car void the warranty. I don't even think it is legal to completely void the entire warranty of the car. The real question should be 1) whether the modification is likely to cause an issue that would cost a significant amount, and 2) whether that mod is likely to cause Porsche to deny a related warranty claim.

No one can answer that question with absolute certainty in advance. Factors in the decision include things like which dealer you take it to and what your relation is with them, how is the local PCNA service rep feeling that day, what is the nature of the problem, and how much is this repair estimated to cost. The answers here are not black and white.

All that said, read up on other owner's experiences with the same or similar mods. How many off the shelf ECU tunes from reputable companies are blowing up engines? If the answer is none, then performing that same mod is unlikely to give you problems and therefore you are unlikely to ever even need to face a warranty coverage question with the dealer/PCNA/Porsche. And how often have you heard of Porsche completely voiding a warranty due to a mod? Some service departments will look for mods in order to use it as ammo to defend a denial of a warranty claim, but again this can come down to your relationship with said dealer more than any actual facts.

I'm not picking on your specifically but I have seen this fear of total warranty annihilation from so many owners and few even understand how the warranty, a legal contract if I'm not mistaken, even works. Do your due diligence before doing any modification and make your choice, but don't assume one mod is going to suddenly make any manufacturing defect your own personal problem.
