The EnviroVent CCV kit is a simple and cost effective CCV system for your Cummins B, C, & L series marine diesel. The Envirovent was designed to be the perfect and simple upgrade replacement for the very troublesome factory supplied Walker System that can cause so much unnecessary grief on any C or L series Cummins.

Note: parts & components shown in the image are not necessarily representative of the parts required for your specific engine model.

Note:  The QSC Turbo has a very tapered inlet.  The S&B air filter works just fine, we have a lot of customers running these without any issues. But be aware that the filter may not tighten up and “Feel” like its on there super solid.  A little blue rector seal or something sticky helps a lot.
