I just wanted to complement JLT for making an excellent part. I put their oil separator on my 2015 Mustang GT 5.0 when I got it last March. I don't drive it much but just went over 2000 miles and had it on the track last weekend. I changed the oil yesterday and checked the oil separator and was a bit surprised to find 2-3 tablespoons of oil in the can. On the street I don't drive it hard but on the track I did. The track time might have accounted for some of the oil in the can...wish I had checked it before I went. Anyway I thought you all might like to know this nicely made part is doing a good job. All that oil would have made it's way into the intake manifold and back through the engine so I'm glad I installed it when I got the car.
