You could always get a custom one made up as well if you like fibreglass If you want to cut it up, my advice would be to add some bonnet vents (not a bonnet scoop as the intercooler is water-air anyway) that way you can reduce the under-bonnet temp. and increase the flow through the engine dramatically.
If you just wanna add sideskirts and stuff then SSV will be able to fulfil your needs.
