I just installed a custom intake I got from rotaryextreme.com, and i'm not sure what to do with the three 3/4" hoses which were previously attached to the stock airbox.

i know two are for the BOVs, but the third one is a mystery, and it's loud as f*&K the way I have it now. right now, all three hoses are open under the hood, and everything's running great, but the third hose expels air (it comes from the upper passenger side of the engine) and is really loud - it seems to do it in correspondence to the BOVs operating. It kind of sounds like my car is farting. What should I do with that 3rd hose?

Actually, should I do anything with the two BOV hoses, or just leave em open? AND, what should I use as mini airfilters on them?

Thanks!

 

K&N crankcase filters on the hoses, and I'm done.

My first mod, and now I want MORE! BWA-HAHAHAHA!!!
