yes, the intake was basically custom built and i didnt feel like welding a piece in order to connect that tube,so i replaced it with the filter which works just as well.

did you get any performance or anything like that by replacing the tube?

It's just a breather. In stock configuration (as you know) the tube is connected to the intake and uses the vacuum to suck out gasses that form in the engine block. now, no vacuum and it's all left up to the pressure in the engine block to expel the gasses. I would think that if anything (however small) it would be a decrease in performance, though I'm quite sure not detectable.
Stick w/the intake hose if you can.

yea i would have liked to use the hose but i too got a POS off ebay so i had to improvise. im thinking about getting rid of it and getting a legit CAI just because the raw statistics that prove that CAI is better than SRI, although after installation the new sound was awesome and i did feel a difference in my low end torque around 35000 RPM, im just scared that if i go to cold air that my power may decrease? but im wondering what works better with what. CAI with exhaust sounds healthier than SR with exhaustjust because colder are is being ingested and heated up along the way opposed to already hot air getting even hotter along the way..i dont know. im still debating. may just get exhaust and see how things go from there see if i wanna switch after that.

I doubt, and tried to make clear in my post, that any power losses from not using the recirc hose are extremely minimal, but is overall (imo) a bad idea, but not a detrimental one. The hose and vacuum for the intake actually help to reuse, unspent gasses (blow-by) reducing emissions, keeping the oil cleaner and may actually improve fuel economy a miniscule amount. That's all I meant.
