hi mate.
this is a pic of my engine bay, as you can see i have just the rear part of the heater blower cover and i am going to make a smaller front section just to cover the blower and fit a air feed pipe so it sucks in cold air rather than engine air which makes it smell inside the car.
i will make one for mine in about a week then i will make some more and let you know when they are done.
they will make the engine run cooler as the vent in the bonnet can be used to expell hot air
