[Product Features]: Logo New A-Premium Intercooler charge air cooler, compresses air from the turbo and cools it down before it reaches the engine. This increases engine potency and tool

Why Upgrade or Replace the Factory Intercooler?

Turbocharged diesel engines generate significant heat under load.

As intake temperatures increase:

• Air density decreases
• Power output drops
• Exhaust gas temperatures rise
• Turbo efficiency declines

A properly functioning intercooler helps cool compressed air before it enters the engine.

Direct-Fit OE Replacement

The A-Premium intercooler is designed as a direct replacement for the factory charge air cooler.

Benefits include:

• Factory-style fitment
• OEM mounting locations
• No custom fabrication required
• Straightforward installation

This makes it ideal for work trucks and daily drivers.

All-Aluminum Construction

Core Material

• Aluminum

Tank Material

• Aluminum

Benefits include:

• Excellent heat transfer
• Corrosion resistance
• Improved durability
• Long service life

Unlike some factory intercoolers that may incorporate plastic components, aluminum construction offers greater durability under boost.

Intercooler Specifications

Core Dimensions

• Height: 27.5 inches
• Length: 23.56 inches
• Thickness: 2.25 inches

Air Connections

• Inlet: 3 inches
• Outlet: 3 inches

The generous dimensions provide substantial cooling capacity for both stock and upgraded diesel applications.

Helps Reduce Intake Temperatures

Lower charge-air temperatures help:

• Improve combustion efficiency
• Support stable boost pressure
• Reduce thermal stress
• Maintain consistent power

These benefits become especially noticeable while towing or hauling.

Great for Towing Applications

Cummins trucks spend much of their lives under load.

Common scenarios include:

Trailer Towing

Helps maintain power on long grades.

Equipment Hauling

Improves cooling during sustained boost conditions.

RV Towing

Supports consistent engine performance.

Commercial Use

Reduces thermal stress during daily operation.

Supports Factory and Mildly Modified Trucks

This intercooler works well with common Cummins upgrades such as:

• Tuners
• Intake systems
• Exhaust upgrades
• Boost tube upgrades
• Mild turbo modifications

For extreme horsepower builds, larger aftermarket intercoolers may offer additional benefits.

Common Signs of a Failing Intercooler

You may need a replacement if you notice:

Boost Leaks

Loss of boost pressure and reduced power.

Excessive Oil Residue

Oil accumulation around intercooler connections.

Damaged Cooling Fins

Road debris can reduce efficiency.

High EGTs

Elevated temperatures under load.

Reduced Towing Performance

Loss of power when hauling heavy loads.
