Hi
Carbon fibre bits in the engine bay pretty expensive
I bought a carbon fibre cover and air box, never even fitted the air box as I thought it was poorly made and didn't fit but it turned out my engine mounts were gone which changed the height of the engine and the clearance at the main engine air intake, they are now both gathering dust in the garage.
If money was no object I would be looking at Carbonio items, see the ebay link below, googling might bring up cheaper sources
