a professional installer would steam the wrinkles out. All leathers seats have wrinkles untIl they go out on their own in the heat or they are steamed out
i see pictures of valves with a catch can and they are clean but never a picture of valves without a can with truck with same mileage. If these are really needed I cant believe a vendor hasnt done a side to side test, one truck with a can , another without and posted the results after so many miles. Maybe there is a reason they havent ???
