Crank Case Filter Mod
Ignore the blue circle in the picture. Notice how there is a filter on the valve cover and a filter on the intake pipe? From the factory there is a tube that connects the valve cover to the intake manifold. Again, hot air is bad air. Remove the line connecting the pipe to the valve cover. You have to put a filter on the valve cover side, as shown in the picture. As for the intake side, you can either put a filter on it or cap it off.
