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 24V 5.9 cummins exhaust manifold allows for maximum airflow while cooling your engine.
Includes stronger coupler than the stock 24V 5.9 cummins exhaust manifold uses.
The stock 24v Cummins intake elbow 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 24V 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.
