I was wondering about the breather cap. Is it like the K&N filter were you have to clean it after a certain mileage? It seems like it's made from the same material? If so, do you use the same kit as the K&N to clean it? If it's not cleanable, when should you replace it?

I don't clean mine as it will fill back up with oil vapors right away. I don't think it's a problem leaving it as is.

Id have to say ... clean it......... just make shure it doesnt get caked up.... with dirt

 

Mines been on for over 4 months now and still looks pretty clean. I imagine it would be as simple as cleaning any K&N filter though.
