The same brand, K&N.



K&N is snake oil. No real benefit, lets more junk in. May not matter if the motor isn't real. :-)



We're talking about the filters, not the oil. Compared to the spec Moto Guzzi filters, the K&N's

probably do just as well at filtering. Plus, it's not a major mechanical nightmare to change the air

filter.

I'm talking about the K&N filters. They may flow slightly better than stock filters, but let larger particles through. Unless you are running a race engine that's full throttle most of the time and gets rebuilt frequently, there's no benefit. After all, trhe vast majority of your running time is at partial throttle, and the stock filter can easily flow that much air. You do get a bit more intake noise, though!
