New cold air intake

[94preludeSI]

i just installed a new intake on my car and i had two hoses coming out of my stock air pipe and i only have one place to put 1 hose. i put the big one coming out by the sparkplugs on to it and i have another one that is near the top of the intake and its small and i have no idea what to do to it i really need some advice. also, my engine is a hell of alot louder. not from the intake filter not the hissing, the engine itself is louder than it sounded before

Thats weird. The intake should have come with all the proper fittings to put the hoses back into. One should not just be sitting out, even though it probably jus runs back to a regulator. The engine always sounds louder though when you put on an intake because the stock air box is what keeps that engine sound muffled. Plus more air is going into the engine now so it will run better.

dude thanks what you said really made me feel better cause i didnt want to mess anything up and i was just a little worried with how much louder my engine was

Buy a "T" fitting, use it to plug both hoses in to, then plug that into the intake

Observe my crappy ASCII drawing, the red represents the t fitting you need

Yea you need a 3/8" t-fitting and it should work....

the hissing is normal simply because the engine is letting more air in. As for the hoses...as long as you dont have a vacuum leak, they really arent important to hook up.

I had that same problem when I installed the intake, so I took it out. I think one of them is for the EGR connected to the resonator, and the other one connects to the intake manifold. I tried plugging up those vacuum hoses with caps.

Also something bad about not connecting those 2 extra tubes, I noticed that the rev sustains a second longer all by itself. Meaning, you bump the gas, but the engine keeps reving for 1 second longer.

As for the engine getting louder, probably because the ECU isn't used to this change

Im pretty sure you could just buy a breather filter and stick it on the end. Those are the little bity cylnidrical filters you see on some high powered domestics or harleys etc. Goto jcwhitney and find one. Correct me if I'm wrong, but All they really need is filtered air, (I dont think the pressure sensor is outside the tube until you buy an aftermarket one), so just make sure they dont get a bunch of dirt in them by filtering them somehow.
You might be able to find one at an auto parts store (whitch I would suggest), but look on jcwhitney.com and search for breather filter if you dont know what they are.

NO, the reason his engine sounds louder is because the plastic stock air box and tubing keep the sound muffled. Thats why it is used by OEM manufactorers. It's a trade off, less airflow and performance for a lot less noise. Joe consumer wants a quite car, and in general will accept less performance for this to a certain extent. Thats why the OEm's use this design. The CAI will flow more air, cooler denser air, so it will make more noiser right there. To add to it, the metal intake tubing is a lot louder. It doesn't muffle the sound like the crappy stock plastic peice, it is designed to smoothly flow a greater amount of air. The stock peice is designed to muffle sound and keep quite. The metal resonates the air differently, not muffling the sound like the stock peice. The result? A lot louder sound and more noise (besides the better air flow and cooler, denser air for the CAI). This louder sound is normal with any CAI or a short ram intake. It has nothing to do with the ECU "not used to the change." It has everything to do with the sound no longer being muffled, since the stock plastic intake designed to muffler sound is gone, and in its place, metal tubing, which resonates differently and is much louder. It's normal and perfectly fine.
