Huh? You're kidding right? It's just a breather to put the non-needed hoses into.

I suppose it could help a little by not having those hoses piped into the intake itself and creating little non-smooth section of the tube inside, but hell...

Have you ever looked in the inside of the intake tubing? Over time it gets coated with oil, as does the throttle body. The catch-can eliminates this, and keeps those nasty vapors away from your MAS. I am having one added to my Minnam Turbo Intake, along with the heat shield and vent block off spacers.

I don't know why, but oil vapour in your intake charge increases the likelihood of detonation. As well, if oil coats the inside of your intercooler, it reduces the efficiency of it. Two very good performance reasons to run a breather or catch can.

So can I get the catch can and use it on the Minnam intake on a NA motor? I have seen my friend's setup (Minnam intake) and he uses CLEAR tubing, and the one hose leading to the T joint is grimy with oil. So can I use the catchcan and eliminate the oil getting back to the intake system? My car is a MY00 btw.

You can use it on a n/a car, but it is not as necessary I would say. Turbo cars have much greater blowby air passing the rings and going into the crankcase which forces more air and oil through the breather hose.

It is more useful on a n/a car to put the catch can at the PCV valve (although most people don't do it) and not the breather hose though.

CUSCO makes a very neat looking oil catch can also. It has dual hose entry for both heads PVC valves.
