Product Description

The Mishimoto MMBK-RAM-03BK Factory-Fit Boot Kit is engineered specifically for 2003-2007 Dodge/RAM 2500 and 3500 trucks equipped with the 5.9L Cummins inline-6 diesel engine. These trucks often experience wear and failure in their intercooler boot couplers due to exposure to high heat, pressure, fuel, and oil. This kit replaces the factory boots with a set of high-quality silicone boots built with Mishimoto's DuraCore™ multi-layer technology, offering superior resistance to thermal and chemical breakdown while preventing blowouts and boost leaks.

Each silicone boot matches the factory piping dimensions for a direct replacement that installs easily with common hand tools and requires no cutting or modification. The included constant-tension T-bolt clamps ensure a secure, uniform seal that maintains integrity through thermal cycling and high boost conditions. This boot kit is ideal for owners who want to restore reliable intercooler connections, prevent downtime from failed boots, and maintain smooth power delivery from their Cummins diesel engine. The Mishimoto Lifetime Warranty provides added confidence in long-term durability.
