Banks Dual Heater Upgrade Kit

Every thing fit and worked as it should , happy with fit. Fuel mileage improved, when no load on engine. It takes 8 hours ,plus to install kit first time . Noticeable power improvement seen also. Worthwhile product for Cummins engine.

To early to tell if how it will be for cold weather as we are finishing our 4th winter this month. I feel it was a worthy upgrade to spend on, the mechanic installing it said he did another recently with one heater and it struggled at about -18c.
