So, as I was checking my air filter yesterday I noticed my stock intake tube is dry rotted and cracking. The more I moved it, the worse it got. I guess I'll put an aluminum "cold air intake" on since something has to be done. My question is, there are two lines coming off the intake tube before the throttle body. A cold air intake pipe does not have the fittings for those lines. Can I simply put one of those small, crankcase breather filters over them? What is their purpose, anyway?
I've seen some aftermarket intakes with a single line coming off of them, but I've never seen one with 2 lines.
