Ken, That kit you are getting from Boyce is only the intake extension for the air cleaner, a small piece of rubber hose for the extension, and 2 hoses for the air compressor and the crankcase breather tube. Also, a couple brackets and clamps are included. basically, its the "external" kit. There is alot more a fording kit, such as under the hood valves, piping, and cables, and it is very extensive, as I have applied them years ago to multi's and Cummins prime movers. So, if you dont have the fording cable in the cab and all the small tubing and valves under the hood, I wouldnt be going through too deep a pond just yet. I have bought that kit from Boyce a year ago, and it was just again, the outside hardware. Its really easy to put on. I have to say it does look really good on the truck though, even if you dont have the full kit applied.
