BMW N63 crankcase ventilation breather hose change 2010 550i gt 4.4l twin turbo

So my wife's BMW has been throwing random codes for misfires. I've changed out spark plugs twice but found cracks in the pcv hoses. I tried to do a quick fix with heater hose but it only lasted a short time before check engine light came back. Today I change out the hoses with new hoses for only $50. Link for Amazon below.
