Yes I did.It idles smoother because you arent pulling in bad oily air from the crank case.That can foul out the throttle bodies as well.You will smell a little oil at idle but cruising, wont know the difference.

has anybody completely blocked off the crank case breather into the air box while doing the airbox mod and replaced the hose with a crank case breather filter instead? Also was there any bennefit?
