this is a quote from a vendors sight:
"Oil contamination derives from the positive crankcase ventilation valve common on most internal combustion engines where vacuum is pulled on the crankcase by the intake or in some cases the throttle body. This contamination occurs when oil vapors exit the crankcase via the PCV valve, enter the intake tract, and create adverse effects such as carbon build-up on valves, pistons, and plugs, as well as cause harmful detonation. Detonation in many cases causes the ECM/PCM to retard timing, thus creating a reduction in horsepower. Power adders such as turbos, blowers, or nitrous can benefit greatly due to the removal of oil contamination in the combustion process. Poor emissions could also be traced back to high levels of oil residue being burned in the combustion process. By removing this oil, a clean burning engine could help the environment as well as improving the performance of a vehicle."
The catch can is placed inline of the pcv system and "catches" the oil contaminants before it reaches the intake tract.
