I dont know if this stuff really works but the vent that goes from the intake to the valve cover does it help at all to take it off and just not have it so the motor vents better...i always thought it made it worse...well let me know i just heard about it from honda tunings new magazine...id like some pros and cons..thanks

 

is your car boosted? If not, shouldnt have a need to mess with it, unless you like a small smell of oil when driving.

 

its a pcv valve (positive crankcase ventilation) I put a breather on mine since it sends hot air into your intake, if you have a cai or sri than I would put a breather on the valve cover only cause it looks better imo and not needed so far as I know....
