1994-2007 Cummins 5.9L ATS Arcflow Intake Manifold

ATS is the original inventor of the 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 effect. This tumbling effect 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 predrilled and taped holes for anything from a boost gauge, water/methanol injection, propane injection, nitrous, or anything you want to add or monitor.
