Cool Hoses | 2003-2004 Ram 5.9 Cummins

The ULTIMATE intake tube for the 3rd Generation Dodge Ram powered by the legendary Common Rail 5.9L Cummins! DYNO and REAL-WORLD proven to work.
FEATURES & BENEFITS:

• 6- Layers of reinforced webbing with a stainless steel wire wrap for lasting strength and durability
• Silicone rubber construction
• The Cool Hose insulates intake air from underhood heat better than any other aftermarket tube
• Smooth bore hose with long sweep bends to minimize air flow restrictions and pressure drop
• 4” inside diameter throughout the hose
• Superior fit and finish
• Easy to install
• Dyno tested to produce more power than any other aftermarket intake tube. An additional 3.0 HP** (w/ stock fueling) or an additional 5.5 HP** (w/ power box set @ 80 HP) and increased torque throughout the RPM range.

Underhood temperatures can climb to over 150 degrees when towing up a steep grade. Underhood heat surrounding the intake tube will conduct through the tube material and increase the intake air temperature by the time the air reaches the turbocharger. Different tube materials conduct this heat at different rates; aluminum tubes have the fasted heat transfer, followed by steel and then plastic. Rubber has only 1/36th of the thermal conductivity of plastic intake tubes. The silicone rubber “Cool Hose” provides the coldest air to the turbocharger when compared to any other aftermarket intake tube. “Cool Hose” with its true 4” inside diameter and long sweeping bends has one of the lowest air flow restriction and pressure drop designs in the industry.
