Plenty of info out there on how to design your own intake to conform to your specific requirements. I'm going to build mine, but only after I get to the point of finishing my engine bay. I want the intake to incorporate the air filter, utilising the two inlet ducts from the coupe roof as combustion air. Then to the turbo, in thru the intercooler, then to the manifold. I'm hoping to make it aesthetically pleasing, because the engine will be nearly hidden from view. Gotta do the exhaust system too, so fun fun fun!
