Mishimoto Silicone Intake Hose

2003–2007 Dodge Ram 2500/3500/4500/5500 5.9L Cummins

Part #: MMHOSE-RAM-03IHBK

Overview

The Mishimoto Silicone Intake Hose is a premium replacement for the factory air intake hose on 2003 to 2007 Dodge Ram 2500, 3500, 4500, and 5500 models equipped with the 5.9L Cummins engine. Designed to improve airflow and durability, this intake hose replaces the restrictive, ribbed plastic stock hose with a smooth, free-flowing silicone tube. It is engineered for diesel enthusiasts looking to enhance turbo efficiency and overall engine responsiveness without extensive modifications.

By eliminating the corrugated design and integrated muffler found in the factory hose, the Mishimoto intake hose reduces airflow turbulence and increases induction noise, delivering a more aggressive engine sound and improved throttle response. This upgrade is ideal for owners seeking a reliable, long-lasting intake solution that supports enhanced performance and durability.

Key Features

The Mishimoto Silicone Intake Hose offers a range of features designed to optimize airflow and withstand demanding conditions:

• Direct replacement for the factory 5.9L Cummins turbo air duct on 2003–2007 Dodge Ram trucks
• Smooth internal surface eliminates ribbing to reduce airflow turbulence and improve turbo efficiency
• Removes the stock integrated muffler to increase airflow and add a subtle induction sound
• Constructed from five layers of high-quality silicone for superior strength and flexibility
• Embedded stainless-steel wire reinforcement prevents collapsing under high boost or vacuum
• Available in black, with additional color options of blue and red for customization
• Includes durable worm gear clamps for secure, hassle-free installation
• Backed by Mishimoto’s Lifetime Warranty for long-term peace of mind

Construction & Design

The Mishimoto intake hose is expertly engineered using a five-layer silicone construction that balances flexibility with durability. The silicone material resists heat, oil, and environmental wear, ensuring the hose maintains its shape and performance over time. Embedded stainless-steel wire reinforcement provides structural integrity, preventing the hose from collapsing under high airflow demands or turbocharger boost pressure.

This robust design not only extends the lifespan of the intake hose but also maintains consistent airflow, which is critical for optimal turbocharger performance. The smooth interior surface minimizes airflow restrictions and turbulence, contributing to improved engine efficiency and responsiveness.

Performance & Sound

By replacing the factory corrugated plastic hose and removing the integrated muffler, the Mishimoto Silicone Intake Hose enhances turbocharger efficiency and increases airflow volume. This results in a more responsive throttle and potentially improved engine performance under boost. Additionally, the removal of the muffler adds a noticeable induction sound, giving your 5.9L Cummins a more aggressive and engaging engine note without being intrusive.

Installation & Fitment

Installation of the Mishimoto Silicone Intake Hose is straightforward and designed to be a direct bolt-on replacement for the factory air intake hose on 2003–2007 Dodge Ram 2500, 3500, 4500, and 5500 trucks with the 5.9L Cummins engine. The kit includes all necessary worm gear clamps, allowing for a secure and tight fit without the need for additional modifications or special tools. This makes it an ideal upgrade for both professional installers and DIY enthusiasts.
