Carbon fibre internal engine covers

Anyone know where to source them ?

Have sourced the Lotus OEM ones , weren’t fitted to my car as standard , bizzare .

They have stopped fitting them now, weight / cost saving I expect

Had the OEM ones fitted today , GBP 209. , cheers Lotus for taking em off in the first place !

So … the covers are made out of the most horrible gritty plastic and I want to wipe clean em , EVERYTHING rasps and clings to them , what material to clean them ? Cheers !
