Sometimes it pays to be a little creative
You may call me cheap, but the ~ $220 or so that the XKR's intake duct costs is too much for what you get. It's plastic, it's inefficient thanks to all those resonators, and it has a habit of breaking into pieces after 10 years, mostly at the accordion. However, in my case, the resonators were also crumbling. While I would ideally would've liked to get an all aluminum intake, my student's salary (or lack thereof) restricted that.
Instead, I got an 3" diameter elbow (I think it was 40º angle) made out of silicon, a 5 inch long, 3 inch diameter pipe from a muffler shop (for free), and a coupling, also in 3" diameter and 3 ⅛" diameter at the other end. Unfortunately that coupling hose is blue because the shop was out of other colors for that size. I took a hacksaw to the old duct, sanded down the edges on both the old duct and the pipe. Eventually I want to replace the pipe with an aluminum one. In the process I removed three resonators. Now I have no air leaks, no codes, and saved myself some money.
The result, may not be the prettiest, but it is functional and cost me just $40 all in:
P.S. I know the engine compartment is dirty. It's on my to do list.

Your work-around is doing something else (fine for you).
Yeah, you're cheap, but you've your reasons and anyway it's your car so you can do as you will.

Very inventive and good to hear it's working efficiently.

Interesting. I drove the car today and noticed no loss or noticeble gain in power. The throttle does feel a little more quick to react. Likewise, I also noticed no difference in sound. Only 3 of the 6 resonators were lost. All three of the resonators that were lost were all crumbling. The other three that are closer to the throttle body are still intact, and in place.
My goal was not to add intake sound or remove airflow resistances. My goal was to repair the intake duct and get rid of P0171 and P0174 for a reasonable amount of money. Mission accomplished. However, since I plan to keep this car until my retirement in 55 years or so if possible I do want a solution that will last the life of the car.

EV conversion? Over my dead body. That would mean giving up that 4.2 Supercharged V8 and the glorious exhaust note I have. Dad got the center resonator replaced with an X pipe, deleted the before rear axle mufflers, and the post-rear axle mufflers have been replaced with Magnaflows. He also did the under axle conversion. About all it needs is the Nameless performance cats to finish the exhaust upgrades, but I think that may be too much.

I remember that one manufacturer is already piping in "automotive" sounds through the audio to give their EV more familiar ambiance. Forget which one though.
Perhaps you should record your exhaust sound for future use.

Odds are the EV would outperform the 4.2SC. On the E-Type factory conversion they had to "de-tune" the power/performance to avoid rework of the original chassis.

Performance at the sacrifice of soul and character is to me a deal-breaker.

A couple of years ago, the Tesla company sent two sales reps and a vehicle to demo at our annual air show. I got to drive it and was very impressed with the performance.I mentioned to the reps that if they could utilize the audio system to produce the sounds of a revving V8 I would buy one. They smiled and said no!
