The ATS 2019012272 ArcFlow Intake Manifold for your 03-05 Dodge 5.9L cummins is the original arc shaped intake manifold, to which set the standard across the industry. The ArcFlow dynamically directs air into the intake manifold with a gradual expansion chamber designed for maximum flow and minimum turbulence. By allowing the air to gradually expand, as opposed to an abrupt expansion, the air will continue on its path without a "tumbling" affect. This tumbling affect slows the air flow and creates a restriction. With the ArcFlow, you will experience lower EGTs, quicker turbo spool up, and better throttle response.
The ArcFlow includes pre drilled and taped holes for any thing from a boost gauge, water/methanol injection, propane injection, nitrous, or anything you want to add or monitor.
