I got one because I don't want oil where it shouldn't be. after putting it on I realized I'm catching way more than I thought I would be. My car has 16k and Ive had a catch can for probably 10k of that. I caught at least 8 oz of oil so far. The boss 302s has one. The fr500s have one. The cobra jet has one. It obviously does something that's good for the motor.
Ford recommends one if you get the procal tune or the trackey tune.
