Any interest in a lightly ported and thermal coated M272 intake manifold?

I lightly cleaned up the intake ports and thermal coated the top and bottom to help reflect heat. This allows for a cooler intake charge. We do this for all of our M112/M113 manifolds. The color of the manifold is black.
I'm looking for $500.00 for it. A stock manifold from MB is about twice that much. This is brand new.
This will work on C300 and C350
