Description

The result is a substantial increase in torque density, improved turbo response, broader powerband efficiency, and repeatable performance under sustained load, all while maintaining daily drivability and smooth OEM-like operation.

Engineered for enthusiasts seeking a complete Audi S4 or Audi S5 B9 3.0T performance upgrade, the RED Package Bundle delivers increased horsepower, significantly stronger mid-range torque, faster turbo response, and consistent power under sustained boost — all within the limits of the factory turbocharger system.

Cold Air Intake Systems

Increased Airflow Efficiency & Turbocharger Response

The factory airbox is engineered for noise suppression and emissions compliance, not maximum flow. Upgrading the intake system improves the turbocharger’s ability to draw in air efficiently, reducing pressure drop before the compressor and enhancing throttle response.

Available Options

AWE Carbon Fiber AirGate Intake
A premium carbon fiber intake system designed to balance airflow performance with thermal shielding. The AirGate design allows users to configure the intake as a sealed system for temperature control or partially open for enhanced induction acoustics. The carbon fiber housing resists heat absorption and maintains structural rigidity under load.

Untd. Performance Cold Air Intake
A high-flow, open-element intake system designed for maximum volumetric efficiency. Engineered inlet geometry and filter placement promote unrestricted airflow while maintaining stable intake air temperatures during real-world driving conditions.

Performance Contribution

• +8–17 HP (supporting modification when tuned)

• +8–16 lb-ft torque

• Faster turbo spool

• Sharper throttle response

• Enhanced induction sound characteristics

While intake upgrades alone provide modest gains, their primary value lies in supporting higher boost levels required for Stage 2 calibrations.

Downpipe Systems

Reduced Backpressure & Accelerated Turbo Spool

The factory downpipe contains restrictive catalytic material that limits exhaust gas flow immediately after the turbocharger. Upgrading the downpipe significantly reduces exhaust backpressure, allowing the turbo to operate more efficiently and achieve target boost levels sooner.

Available Configurations

• Untd. Performance Catless

• Untd. Performance Catless with Integrated Heat Shield

• Untd. Performance 200-Cell High-Flow Catalytic Converter

• Untd. Performance 200-Cell High-Flow Catalytic Converter with Integrated Heat Shield

Catless Downpipe
Provides maximum exhaust flow and the most aggressive performance gains. Designed for off-road use where regulations permit. Delivers the fastest turbo response and strongest top-end power potential.

200-Cell High-Flow Catalytic Downpipe
Balances performance and emissions considerations. The 200-cell catalyst dramatically reduces restriction compared to OEM while maintaining a more refined exhaust tone and improved compliance characteristics.

Heat Shield Variants
Integrated shielding improves thermal management within the engine bay, reducing radiant heat transfer to surrounding components. Power output remains identical to non-shielded versions.

Performance Contribution (with Stage 2 Calibration)

Compared to Stage 1 configuration:

• +20–45 HP increase

• +25–35 lb-ft additional torque

• Noticeably stronger mid-range pull

• Higher sustained top-end power

The downpipe upgrade is the defining hardware requirement for Stage 2 performance levels.

Intercooler Systems

Thermal Stability & Power Consistency Under Boost

As boost pressure increases, so does charge-air temperature. The factory intercooler core can become heat-soaked during repeated acceleration runs, resulting in timing reduction and power loss. Upgrading the intercooler ensures consistent intake air temperatures, preserving ignition advance and boost efficiency.

Available Options

Untd. Performance Intercooler with Charge Pipes
A high-capacity bar-and-plate core combined with upgraded charge pipes to minimize turbulence and pressure drop. Designed for high-boost applications and aggressive driving conditions.

IE Performance FDS Intercooler
Utilizes advanced core engineering to optimize airflow distribution across the cooling surface. Focuses on reducing pressure drop while maximizing thermal transfer efficiency.

Performance Contribution

• Maintains rated horsepower during repeated pulls

• Reduces heat soak

• Stabilizes boost pressure

• Supports full Stage 2 torque output

Intercooler upgrades do not independently increase peak horsepower but are critical for maintaining performance consistency, especially in warm climates or performance-oriented driving.

ECU Calibration Options

Optimized Boost Control, Ignition Mapping & Torque Management

The ECU calibration is the central component that unlocks the performance potential of upgraded hardware. All available tuning platforms are engineered specifically for the EA839 engine architecture.

Stage 1 Calibrations

(Compatible with Stock Downpipe)

Available Options:

• IE Performance Stage 1

• Jackal Motorsport Stage 1

• TuneZilla Stage 1

• COBB Accessport Stage 1

Estimated Output (93 Octane Fuel)

• 400–420 HP

• 480–510 lb-ft torque

Estimated Gains Over Stock

• +50–70 HP

• +110–130 lb-ft torque

Stage 1 significantly increases low- and mid-range torque, delivering immediate throttle response and improved acceleration while retaining factory exhaust hardware.

Stage 2 Calibrations

(Requires High-Flow or Catless Downpipe)

Available Options:

• IE Performance Stage 2

• Jackal Motorsport Stage 2

• TuneZilla Stage 2

Stage 2 with 200-Cell High-Flow Downpipe

• 441–459 HP

• 522–543 lb-ft torque

• +93–106 HP over stock

• +152–175 lb-ft over stock

Provides a strong balance between performance and daily usability.

Stage 2 with Catless Downpipe

• 456–478 HP

• 543–571 lb-ft torque

• +111–124 HP over stock

• +162–186 lb-ft over stock

Delivers maximum airflow efficiency and the most aggressive acceleration characteristics within the factory turbocharger’s limits.

Driving Characteristics After Installation

With the RED Package Bundle configuration:

• Turbo spool occurs earlier in the rev range

• Mid-range torque becomes substantially stronger

• Throttle mapping feels more immediate and precise

• Highway passing power is significantly improved

• Power delivery remains smooth and predictable

The EA839 platform responds exceptionally well to airflow and calibration improvements, making this one of the most rewarding modern Audi engines to upgrade in stock turbo configuration.

Intended Application

The RED Package Bundle is ideal for:

• Performance-focused daily drivers

• Enthusiasts seeking reliable 450+ HP capability

• Owners preparing for future turbocharger upgrades

• Drivers demanding consistent power under real-world conditions

Important Considerations

• Power figures vary based on fuel quality, elevation, climate, and drivetrain loss.

• Catless downpipes may not be emissions compliant for street use in certain regions.

• Professional installation is recommended.
