OK... gotcha, didn't have my thinking cap on HD only for me. They are specked for the engine they are going on and that's good enough for me.
H-D oil filters all the way for now. Trying to do some research on the Amsoil oil and air filters. Any info on them would be appreciated. Heard good things about Amsoil products and wonder if they are as good as people say or just hype coming from the independent dealers.
When i switched to amsoil 20W50 I picked oil up at harley dealer. I asked for what he thought was best filter. He handed me a amsoil oil filter said it was manufactored to work best with syn oils.Go figure.
