The ATS 2019012218 ArcFlow Intake Manifold for your 98.5-02 Dodge 5.9L Cummins will increase flow, performance and efficiency. 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" 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.

downright simple to install. A ton of pre drilled holes to hook up whatever you want (pretty darn convenient). I coupled this thing with a farmboy diesel grid heater delete and you can def. feel the boost come on sooner...way sooner. And now the left side of the engine has a nice whistle to it too...or a boost leak.
Did what i expected

Good product takes like 10 mins to put min helps on bringing the boost on earlier and has 5 port holes for meth/water, nos, and gauges. Plus looks sweet on the top of the engine
Awesome product
