an oil catCh can, is used to capture moisture, oil, and blow by gasses that would go into your intake system and build up carbon and sludge. Basically, you don't really need one. It's most of the time just used for engine dress up and nothing really performance oriented, but i guess it could help. They are not really specific for your engine so anyone should work.

It's definitely not just an engine dress up item. A lot of vehicles have a poor PVC system that results in excess oil droplets and vapors being pulled into the induction system. Along with sludge and gunk in the induction piping, throttle body, and intake manifold, this can also cause other issues such as fouling and sticking of the IAC, and more importantly the excess oil/vapors being burned can and will cause pinging and knocking during the combustion process as well as being mis-read by the O2 as excess unburned fuel, in which case the computer will lean out the fuel mixture quite possibly creating dangerously lean condition.

Now, not all vehicles are at risk of these PCV issues. Keep an eye on your system, and if you start seeing the oil and build-up, do a home made Catch Can as a test and see what happens. A simple Air/Water separator for air compressors available at Lowes, Home Depot, or Sears works like a champ and is easily plumbed in-line with your PCV lines on the car. The advantage to the commonly available air/water separators is that they have glass viewing windows to actually see if you're catching anything.
