I have only seen on set of valve covers that hid the coil that were kinda cool, but they cost like 1200 bucks from Billet Specialties.
We sell a coil bracket to mount the coils on to that will let you mount the coils where ever you want. You will need an extension harness and and some custom plug wires but to me that makes a much nicer install. And opens the doors to put ay valve cover you want on the engine.
Most of the coil covers seem kinda cheesy.
