How often should I clean up my intake? I have a bbk and I have not clean for about 10 months or so. How do I know I have to replace the filter? i wash my filter with the K&N intake kit.

 

I clean mine about ever 6000ish miles or every other oil change

 

K&N always says their filters last something like 50,000 miles before they need to be cleaned but I'd clean it every 10k or so.

 

I think I’m going to clean it this weekend to be on the safe side. How do u know to replace the filter?

 

when it falling a part!! jk when u can see holes in it or if u look in the intake pipe and see a lot of dirt in it or ur mass air looks dirty i say about 50,000 miles u should buy a new one to be safe i have the BBK intake and sents the filter sits in the fender well it gets a lot of dirt from the street kick up from the car in front of you and if ur like my bro he rides people *** and his filter gets dirty FAST so dont ride people *** lol
