Intake Horn

2007.5–2009 Dodge Ram 2500 & 3500 6.7L Cummins Air Intake Horns

Eliminate restrictive factory airflow bottlenecks, improve turbo spool-up velocity, and maximize air distribution across every cylinder with premium 2007.5–2009 6.7L Cummins 3rd Gen air intake horns from Full Force Diesel. Heavy-duty Ram 2500 and 3500 trucks working under severe commercial workloads, pulling heavy trailers, or running custom engine tuning struggle against the tight, pinched turns and small inner diameter of the stock cast-aluminum intake horn. Over years of service, the factory grid heater setup and restrictive plenum entry create turbulence that chokes airflow right before it enters the intake manifold. Upgrading to a high-flow, mandrel-bent or cast-aluminum performance intake horn opens up the final stretch of your induction tract.

Advanced Airflow Dynamics: Smooth Inner Diameters and Plenum Volume

Transitioning away from a restrictive factory intake horn to a high-capacity performance upgrade completely transforms your engine's breathing efficiency:

• Wide-Diameter Internal Transition: High-flow intake horns feature smooth, computer-optimized inner contours that eliminate the sharp 90-degree turbulence points found in stock castings, allowing compressed charge air to rush effortlessly into the engine.

• Multiple NPT Port Options: Engineered with pre-machined boost and water-methanol injection ports, making it simple to monitor drive pressure, inject auxiliary cooling fluids, or install boost gauges without drilling into your factory piping.

Rugged Billet Construction and Secure Sealing Hardware

Our selection of air intake components features robust hardware engineered for absolute boost retention under high pressure:

• Heavy-Duty Cast Aluminum and Billet Construction: Built from thick-wall aluminum alloys designed to withstand extreme boost pressures without ballooning, cracking, or leaking at the flange.

• Secure O-Ring and Gasket Seals: Supplied with high-temperature replacement O-rings or heavy-duty gaskets and hardware studs to ensure a completely airtight seal against your factory or aftermarket intake plenum.

At Full Force Diesel, we carry the rugged, street-tested mechanical hardware and machine-shop-certified components your transitional 3rd Generation inline-six needs to feed air efficiently.
