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.


  • Non restrictive airflow design
  • Increases intake efficiency
  • Increases air velocity
  • Eliminates air turbulence
  • Increases throttle response, torque and horsepower
  • Increases fuel economy
  • Gains up to 15 horsepower and 30 foot pounds of torque

all product claims are true. I was a huge fan of this product for the two years that it was on my Dodge. Until the bolt hole (right above the T in ATS)fatuiged and cracked due to thin casting around that area and metal fatuige. No,I did not over tighten the bolt.

Very nice piece. I have purchased several ATS items and this one is great as well. Twice the size of the stock intake, multiple ports on the back side, quality is great and looks great!! Two thumbs up.
