This kit is a complete crank case ventilation kit. This will alleviate blow by which 6.7's are known for. Will also cause for less Diesel sludge getting clogged in the motor causing for worse fuel economy and worse performance. The vent will run down towards the frame of the truck and dump to atmosphere at which you'll see occasional puffs of smoke come from underneath the truck.
American made billet plates, Phoenix AN fittings, stainless hardware, and high quality 3/4" hose. Bolt on setup, no cutting drilling, or shaving necessary.
