We developed these 5.5" x 5.5" Cooler Ducts to perfectly fit certain coolers and allow you to efficiently duct cooling air to them no matter where they're mounted. This will open up options for you when you need to add a cooler for oil, differential or transmission, power steering, etc. This Duct's opening is 5.5" x 5.5". It has a .75" flange around the perimeter, making the total dimensions 7" x 7". The height is 5 3/4" and utilizes a 3" opening to fit standard brake duct/air duct tubing.
This Cooler Duct was developed on Setrab's 50-119-7612, but would also work with any coolers of a similar size.
