M K, the rocker cover is factory black mk6 escort almost like satin finish, i painted the over pipe to match.
I would expect the power to be around 240-250bhp @ around 18-22psi
The reason i use bonnet raisers on the Mk3 is because they didnt have vents as std, none of the cars ever suffer with heat soak etc.. but the hot air is better out than in

Its down to the customers choice anyway..
