I had a 2014 f150 ecoboost, I put catch can on both sides. The driver side had significantly more gunk than the passenger side. I traded the 14'in for a 15' lariat ecoboost and want to put catch cans on it. I see more options for passenger sides. But in my experience the driver sides Getzsmore gunk than the passenger side. I'd likeone for both. looking for suggestions.
