though, isn't the idea to shield the pop from a direct air blast of turbulence that screws up the MAS as many have posted over time? That's why the plastic shield is recommended be left in place isn't it? I often through about getting one of those type panels as some look pretty darn good, but then it might cause issues with a PTU located there if it rains hard plus wouldn't that be a concern if there was a downpour and the intake sucks in large amounts of water...ie hydrolock?
