Carbon fiber valve covers

[5.7 GT1]

I'm in the process of potentially developing Carbon Fiber Upper and lower valve covers for the 911 and 930. The big question is; is there any demand for super high quality Carbon Valve covers?? A set of upper covers would be offered somewhere in the high $600s. I have not yet determined a price for the lowers. I know the uppers would be bullet proof and come with a long term warranty. The weight saving would be minimal, the primary function would be cosmetic. Other ideas that pelican members have shared are o-ring seals and coil on plug mounting capability.

Any feedback would be much appreciated!
