Depend, how much driving do you drive a month? 2k-2.5k?? if so i would change every time you have your oil change. That's the recommended. But i usually change every 2months because i drive a lots so i get dirty pretty quick. So i think you should clean it every 2 or 3 months depending on your monthly driving.
you dont have to change the actual filter just clean it
yeah. That's the good thing about the CAI filter. can be reuse ton of time. Get a cleaning kit for like $10.00. If you want to replace a new one then after the first 1 yr pay attention when you're cleaning. if the filter break off tiny bits of pieces when you wash it, then that's a good time to get new good.
i've cleaned mine twice and I just got it mid last summer. Very dusty up here. Just make sure that you keep a clean filter, cause when it was dirty it drove worse than it did with just the exhaust.
