crank case filter

  1. #1
    Are these crankcase filters made by the likes of pipercross, and green any good?And what exactly do they do?I sorter understand they help you engine breath better! What sorta power gains are you looking at? Would this work well with a viper induction kit?
    How much for one

    they dont help your engine breath better as such, these vent oil vapour and any other gases from teh engine to the atmosphere (illegal: mot fail), normally these vapours and what not are put back into the induction tract and back into the engine. They dont really do very much at all.
