FAQ
How much power will this support?With proper air and a strong lift pump, the added CP3 volume commonly supports ~50 HP over stock fueling. For bigger injectors/turbos, consider a stroked CP3 or dual-CP3 setup.
Do I need to remove the CP3 to install this?No. One advantage of this kit is that installation can be done with the CP3 still on the engine.
Will this work on all 2007.5–2018 Ram 6.7L?Yes, it’s designed for common-rail CP3-equipped 6.7L Cummins trucks (2007.5–2018).
What if I outgrow this kit?Step up to a high-output CP3 or add a second pump. See our CP3 category or consider dual-CP3 options.
