Understanding the Audi 3.0T Cooling System

Although commonly called the “3.0T,” Audi’s engine is actually supercharged.

The Eaton supercharger compresses intake air, creating heat.

Without proper cooling:

• Intake temperatures rise
• Air density decreases
• Power output drops
• Heat soak becomes more common

The charge air cooler helps control these temperatures and maintain consistent performance.

Direct OE-Style Replacement

The A-Premium unit is engineered to replace the factory charge air cooler.

Benefits include:

• Direct-fit installation
• OEM-style dimensions
• Factory hose compatibility
• No custom modifications required

This makes it ideal for owners restoring factory performance.

Aluminum Core Construction

Core Material

• Aluminum

Advantages include:

• Efficient heat transfer
• Corrosion resistance
• Lightweight construction
• Long service life

Aluminum remains the preferred material for charge-air cooling applications.

OEM-Style Plastic End Tanks

Tank Material

• Plastic

Benefits include:

• Factory-style fitment
• OEM-equivalent design
• Proper integration with factory components

For stock and lightly modified vehicles, plastic end tanks perform well within factory operating parameters.

Charge Cooler Specifications

Core Dimensions

• Height: 7.44 inches
• Length: 7.68 inches
• Thickness: 1.02 inches

Air Connections

• Inlet Diameter: 0.79 inches
• Outlet Diameter: 0.79 inches

These dimensions closely match original equipment specifications.

Helps Reduce Heat Soak

Heat soak is a common issue on supercharged vehicles.

Symptoms include:

• Reduced acceleration
• Higher intake temperatures
• Reduced power consistency
• Performance loss during repeated pulls

A healthy charge cooler helps maintain consistent cooling efficiency.

Common Signs of a Failing Charge Air Cooler

You may need replacement if you notice:

Coolant Leaks

Internal or external leakage can reduce cooling effectiveness.

Reduced Performance

Higher intake temperatures may cause noticeable power loss.

Check Engine Lights

Cooling-system-related diagnostic codes may appear.

Heat Soak Issues

Performance may decline after repeated acceleration runs.

Physical Damage

Road debris or age-related deterioration can impact performance.

Ideal for Daily Drivers

Most Audi A6 owners prioritize:

• Smooth performance
• Luxury driving comfort
• Reliability
• Long-term ownership

A properly functioning charge air cooler supports all of these goals.

Great for Tuned 3.0T Vehicles

The Audi 3.0T engine responds extremely well to modifications such as:

• ECU tuning
• Pulley upgrades
• Intake systems
• Exhaust upgrades

As boost levels increase, efficient charge-air cooling becomes increasingly important.

OE Reference Numbers

This intercooler replaces or references:

• 13810
• AU3012103
• 4G0121212

Always verify OE numbers before ordering.

Installation Considerations

Before installation:

• Inspect coolant hoses
• Check charge-air system connections
• Verify surrounding cooling components
• Replace worn seals if necessary

Because this is part of the charge cooling system, proper bleeding procedures may be required.
