I bought a boost controller off ebay. The only thing it doesnt have is the little air filter that it needs. Does anyone know where i can find one, can i get something similar at like autozone, can i go without it or do i have to go to a performance shop

 

You should get a filter for it though some have claimed not to use it.

you can find it at automotive shops...found some here at Pep Boys.

 

Try motorcycle shops. I've seen many bikes using these filters.

 

Nice catch FD4S. I would've never thought of that one. Thank God for a bunch of guys on this site. It helps having hundreds of thoughts verses 1 or 2!!

 

Run without it for now until you find one. It's not that important.
