Based on technology used in NASCAR air tubes. Elogating through the curve eliminates air shrinkage of cross-sectional curvature tube area. This simply means better air flow through the curve. As air flows around a curve through a tube, the effective tube diameter shrinks as seen by the air, because of turbulence on the inside curve. The longer and sharper the curve the more the restriction. Only the Artic Air Intake Manifold Airhorn, elongates the circular shape of the tube (makes oval), through the curve of the tubular section, allowing for full flow around the curve, instead of the narrowing effect of a round, or flattened tubular design. It means smoother, cooler, air entering your engine.
Our 5.9 Cummins exhaust manifold allows for maximum airflow which cools your engine.
The stock or factory air horn is very restrictive because of the sharp bends, and narrowing between the bolt section, the air must “squish” and compress as it passes through. Many companies flatten their air horns through the curve also, this actually restricts airflow further, being the exact opposite of what air “want” as it goes through a curve.
On a stock 3rd Gen Cummins engine we have seen anywhere from 10 to 20 more horsepower. Modified engines can benefit even more. This will make for better power, fuel mileage, spool-up and cooler EGT’s. Not to mention it looks great to help decorate your engine compartment.
Cast from aircraft grade aluminum, the Arctic Air has four pre-tapped ports in both ¼” and 1/8” NPT, for nitrous, water/meth CNC, boost gauges, etc. for whatever you want to do. CNC machined for perfect fit, and strength to handle any boost pressure you can make. Comes with everything shown in the picture.
FAQ's
Q: My search of intake horn 5.9 cummins shows the Arctic Air. Is this a factory Cummins intake horn replacement?
A: Yes the Diesel Power Source Arctic Air 5.9 Cummins intake manifold is a direct factory replacement for 5.9 cummins intake manifolds. It keeps in place the factory heater grid, which our testing shows still flow well when intact.
Q: How does the air intake manifold compare to Banks air intake manifold?
A: Our test show the DPS air intake manifold flows better than any competitor.

Great product. Can't beat the price! Definitely stands out in the engine bay. I've actually bought one for my 2nd gen and now my 3rd gen. Only issue I had was trying to put the nut on the rear driver side stud. Seems like you have to play with the height of the stud to give the nut clearance to spin on. Might have to use a dremel to make a tad more clearance. Have had the same issue on both trucks. Overall great buy. Won't be my last. Thanks
