For anyone thats interested I have a couple of spare Fibregalss airbox's to suit bike engines. They dont have any trumpet holes cut (photo's show one that has been fitted to hayabusa) and should fit most late model bike engines.
You will just have to look at the trumpet arrangment on your particular engine to see how best to attach to engine.
Any engine that uses rubber style trumpets (such as gsxr1000 or hayabusa) will be easy.
Also comes with k&n panel filter and has black gelcoat external finish and black flowcoat on internal.
