I would have to go the JHP undertank/airbox filter route.

Give john Hacket a call and you might think twice about filters.

You ever taken those filters off to clean, did Lily's a few weeks ago, couldn't believe how many flies and other debris lay inside

I've seen knowledgeable people argue equally strongly for undertank and for in-tube air filters.

I think what it all boils down to is this:

1. Undertank, better filtration and protection for the motor if the tank comes off. More difficult to install on shower type injectors.

2. In air-tube, better performance. Mucho cheaper.

Bearing in mind that Ducati have a performance oriented philosophy for every part of their sports bikes (visible or not), I tend to think that they put their filters in the air-tubes for a good (performance) reason.
