KOROP 6.7L Cummins Upper Air Intake Resonator Tube for Dodge Ram 2007–2018 — Direct-Fit, High-Temp Rubber

This replacement intake hose restores proper airflow, seals the intake tract, and helps maintain engine performance after the factory duct has deteriorated. Built from high-temperature rubber engineered to resist drying and cracking, the KOROP tube is designed to match factory dimensions and mount points so it installs without cutting or modification. It replaces OE reference numbers including 53032944AL and multiple adjacent suffixes, making it a practical service part for Cummins owners.

How does this hose improve my truck's drivability?

A torn, hardened, or leaking intake hose can let unmetered air into the engine and reduce throttle response. Replacing the damaged duct with a properly sealed resonator tube restores consistent airflow and helps the engine run more predictably.

• Restores factory air pathway and reduces intake leaks
• Helps maintain correct air-to-fuel ratios under load
• Improves throttle consistency and reduces hesitation
