This filter adapter has a larger opening, perfectly lining up with a K&N filter. It requires no supports, as they are built-in to the model. I printed out of Carbon Fiber reinforced PETG, and it has been holding up perfectly. Recommend ABS, ASA, Nylon, or CFPETG or something similarly hi-temp. Does not use the stock snorkel. I also recommend getting a tune after this, as the bike runs lean enough stock. This should also fit the Tenere (Ténéré) and FZ-07 - Pretty much anything that uses the CP2 engine.
