I'de use it, it looks like a BMC.
If the airbox is dirty at the next oil change(just a good way/time to keep up with checking/cleaning or replacing the air filter), then use a different air filter.
That one will work fine as a dry filter, but a Very Light coat of aerosol air filter oil on the inlet side wouldn't hurt, as the oil traps dirt, and dish soap and water releases the oil and dirt from the filter material.
The air filter argument came along after the oil and tire threads...and will go on to the end, lol
Just remember how many carburetted bikes have ran filter pods, carb inlet screens, or nothing at all for decades, and run fine.
I'm all for keeping dirt out of an engine, and location/weather/riding conditions make a difference too, and I wouldn't want to ride without an air filter in wet or dusty conditions.
I've also been using K&N and BMC for many years now, and have never had a problem with them.
I ride in all weather and conditions, and like to be able to clean and reuse an air filter.
To me it's easy, and I'm not throwing away old filters.
I bought a used K&N air filter for my '03 Gsxr1k for $17 shipped!
It looks brand new, and was cheaper than an oem air filter.
There's the old hp arguments too, but they are splitting hairs over a couple hp you'll never notice.
However, swapping to an aftermarket air filter you will hear the inlet sound difference, as air is flowing more freely, which tells me, that at high speeds on a tuned bike, and with the ecu's ram-air compensation(that you won't see hp numbers from on a dyno) that there is likely a higher rpm gain in power, although small.
Either way, it's an air filter.
Try it, worst case you swap it for something else, don't overthink it.
