Ok, I want to buy a cold air intake for my 95 Accord EX. I was looking at the stock air intake and I noticed that there are two hoses that connect into the intake and that most cold air intakes I see online only have one place for a hose. What are these two lines for? Do I leave them unhooked? Do I just hook up one? Do both need to be hooked back up? Will it hurt anything if I don't? Please help me out.
