"GReddy Oil Catch Tank catches the oil and moisture in the blow-by gas that causes carbon and sludge build-up in the Intake system and the engine. It keeps the engine clean even under hard driving conditions. It is also an excellent engine dress up item, gives it the race car look with the polished aluminum tank."
Anybody got a photo of how it looks installed? Or a better description of how exactly it works?

The catch can will keep your throttle body and Intake manifold clean, along with the tops of your valves and your pistons. More importantly, it'll keep the IAC valve from getting gummed up, making sure your car always idles properly, and doesn't try to stall when you come to a stop, or start revving up by itself.
It's definitely useful for an NA car. It'll prevent the IAC problem that many people have (bad idle), will keep the engine and Intake system cleaner, and might even give you a bit more power since you'll only be sucking in air, instead of air with gas and oil vapors. You probably won't need to use cleaners (like Seafoam) in the Intake system as much, either.
Doesn't really matter. Any universal one will work fine. If your car is running fine, it shouldn't catch enough oil to overflow between an oil change, or around 5 oil changes. The best catch cans, however will either have the inlet and outlet on opposite sides of the can (usually top and bottom), or use a baffled design. Ones with the inlet and outlet on the same side are kinda useless, since the outlet will just suck the vapors straight from the inlet. Having them away from each other gives the vapors more time to condense so the catch can can hold them. Baffled designs go one step further and give the vapors a longer path through the can. Another thing you can do is put stainless steel scrubbers in the can. This will help force the vapors to condense on them, making the air that's released as clean as possible.

I you use 100% synthetic oil you do not need it. FYI Aircraft (receprecating not turbine) engines that use synthedic oil do not reach their full expected life time between overhauls because they fail compression checks.
