amw catch can?
It keeps oil out of your intake ( gets pretty gunked up after a while), which in the long run keeps the oil from contaminating the fuel in your combustion chamber. Oil lowers the octane level of the fuel leading to detonation. The detonation in the long term damages your pistons leading rebuilds.
So a catch can is actually a pretty nice little thing to have. The AMW unit is awesome by the way. Well worth the cash..
Someone else chime in.. Also do a search.. there have been alot of discussions on this.
