Using that metod will allow not only to run large airbox, preventing need for large opening. It will also allow to use one of standard flat filters like in cars making it cheaper in the long run.
This is a really good idea. A large airbox is capable of making more power than a small one that has been opened up, especially if it has been set up as a properly tuned Helmholtz resonator. And the lithium ion batteries that have become available in recent years definitely help with regard to relocation.
