Cummins ISC Turbocharger Parts Catalog

The Cummins ISC is a proven mid-range engine used across marine, industrial, and heavy equipment applications. One of the most vital components ensuring efficiency and performance is the turbocharger system. A properly functioning turbo not only delivers higher power output but also supports cleaner combustion, better fuel economy, and extended engine life.

This catalog provides a detailed breakdown of turbo-related components for Cummins ISC engines, including air systems, hoses, cleaners, jointing compounds, and support hardware. All items are designed to withstand the rigorous demands of marine and industrial service, ensuring long-lasting durability. With Diesel Pro Power, more than 40,000 satisfied customers worldwide rely on fast shipping, high-quality products, and technical expertise.

Turbocharger & Air Induction Systems for Cummins ISC

The turbocharger system on the ISC engine uses a single turbo configuration. Air is drawn into the system, compressed, and forced into the combustion chamber, allowing more fuel to be burned efficiently. A well-maintained turbo ensures consistent boost pressure, higher torque, and reduced emissions.

Cummins Airsep System – Single Turbo

Designed specifically for Cummins ISC and QSC engines, this Airsep system provides advanced air filtration and induction efficiency. The system is built with a 4-inch throat diameter, making it compatible with standard turbocharger intake housings on the ISC platform.

Key Benefits:

• Enhanced air filtration to protect the turbocharger and cylinders from contaminants.

• Reduced intake restriction for optimal boost levels.

• Extended turbo life and improved engine performance.

• Ideal for both marine and industrial ISC engines.

Whether operating in a harsh marine environment or dusty industrial site, this system ensures reliable airflow and maximum turbo efficiency.

Turbo Mounting & Sealing Compounds

A turbocharger’s performance depends not just on the rotating assembly but also on the sealing surfaces. Over time, exhaust leaks at the turbo mounting flange can reduce boost pressure, cause soot buildup, and lower efficiency.

Hi-Temperature Jointing Compound

Specially engineered for Detroit Diesel and Cummins turbos, this compound provides a reliable seal even under extreme heat and vibration. It is supplied in a 225-gram tube and withstands a temperature range between 550°C and 760°C.

Applications:

• Sealing turbocharger mounting flanges.

• Preventing exhaust gas leaks at turbo joints.

• Assisting with gasket adhesion in high-stress environments.

By ensuring a leak-free connection, this compound helps maintain peak turbo performance and prevents costly exhaust system damage.

Turbocharger Hoses & Connections

Turbocharged engines rely on high-quality hoses to transfer compressed air from the turbo to the intake manifold. Over time, hoses can degrade from heat, oil vapor, and constant pressure cycles, leading to boost leaks or even complete hose failure.

Cummins & Detroit Diesel Turbo Hump Hose

This straight hump hose is designed for 4” x 4” turbo applications and is suitable for both Cummins ISC engines and Detroit Diesel platforms such as the 8V71.

Specifications:

• Upper Diameter: 4 inches

• Lower Diameter: 4 inches

• Flexible hump design to absorb vibration and movement.

Key Benefits:

• Prevents boost leaks by maintaining a secure seal.

• Resists oil, heat, and pressure damage.

• Simple installation with standard clamps.

This hose is essential for maintaining consistent airflow and protecting the turbo system against air loss.

Turbo Air Filtration

Proper air filtration is critical to turbocharger longevity. Contaminants such as dust, salt, or industrial debris can quickly damage the turbo’s compressor wheel, reducing efficiency and leading to premature failure.

Cummins & Detroit Diesel Air Cleaner

Built for industrial and marine engines, this air cleaner has a 5-inch diameter and a 16-inch height, providing maximum airflow while filtering out harmful particulates.

Key Features:

• Durable construction for heavy-duty environments.

• Designed to integrate seamlessly into turbo induction systems.

• Protects turbocharger components from abrasive wear.

This air cleaner is particularly valuable in marine environments where salt and humidity present constant challenges, or in industrial applications where airborne contaminants are present.

Why the Turbo System Matters for Cummins ISC Engines

The ISC engine’s performance relies heavily on the efficiency of its turbocharger. A well-functioning system ensures:

• Higher Power Output – Boost pressure directly increases horsepower and torque.

• Fuel Efficiency – Properly compressed intake air allows complete fuel combustion.

• Reduced Emissions – Cleaner combustion results in lower exhaust emissions.

• Engine Longevity – Balanced turbo operation reduces cylinder stress and improves lubrication flow.

By maintaining all turbo-related components—hoses, air cleaners, seals, and induction systems—operators can extend the life of their ISC engine and prevent unexpected downtime.
