The RED Package Bundle for Audi A8, S8, S6, S7, RS6, and RS7 4.0T EA824 delivers a complete performance upgrade including high-flow air intake, performance downpipes, Wagner Tuning intercooler, and Stage 1 or Stage 2 ECU calibration. Designed for the twin-turbo 4.0T V8 platform, this integrated system increases horsepower, boosts torque output, improves turbo response, and maintains consistent charge-air temperatures under sustained boost. Ideal for enthusiasts seeking reliable 600–700+ HP capability while retaining factory turbochargers and daily drivability.
The RED Package Bundle for the Audi 4.0T EA824 twin-turbo V8 platform is a fully integrated performance system engineered to transform the factory airflow architecture into a high-efficiency, high-output configuration.
Designed specifically for the Audi A8, S8, S6, S7, RS6, and RS7 equipped with the 4.0T twin-turbocharged V8, this package addresses the three primary performance constraints of the OEM setup:
• Intake airflow restriction
• Exhaust backpressure after the turbochargers
• Charge-air temperature instability under sustained boost
Once these airflow limitations are corrected, the ECU calibration optimizes boost control, ignition timing, and torque management across the entire operating range.
The result is a dramatic increase in torque density, sharper turbo response, stronger mid-range acceleration, and sustained top-end performance — all while preserving smooth drivability and OEM-level refinement expected from Audi’s flagship V8 models.
This is not a collection of parts — it is a calibrated system.
The factory intake system is engineered for NVH reduction and emissions compliance. While effective for stock output levels, it introduces measurable restriction under elevated boost pressures.
Upgraded intake systems improve compressor efficiency by reducing pressure drop before the turbochargers, allowing faster spool and more stable airflow at higher RPM.
AWE Carbon Fiber Intake System
A precision-molded carbon fiber intake designed for thermal resistance and structural rigidity under high load. The system balances airflow performance with heat shielding to maintain consistent intake air temperatures while enhancing induction acoustics.
Untd. Performance High-Flow Intake System
An open-flow, performance-oriented intake engineered to maximize volumetric efficiency and reduce airflow turbulence at higher boost levels.
• +10–25 HP (application dependent)
• +10–20 lb-ft torque
• Improved twin-turbo spool characteristics
• Sharper throttle response
• Enhanced induction sound
While intake upgrades alone offer modest peak gains, they are critical for supporting Stage 2 and higher boost calibrations.
The factory downpipes contain restrictive catalytic elements positioned immediately after each turbocharger. This creates exhaust backpressure that limits turbine efficiency and delays boost response.
Upgrading the downpipes significantly improves exhaust flow, allowing the twin turbos to reach target boost more quickly and maintain higher efficiency at elevated RPM.
Untd. Performance Catless Downpipes
Untd. Performance Catless with Integrated Heat Shielding
Untd. Performance 200-Cell High-Flow Catalytic Downpipes
Untd. Performance 200-Cell High-Flow with Integrated Heat Shielding
Delivers maximum exhaust flow and the strongest overall performance gains. Designed for off-road use where regulations permit. Provides the fastest spool and highest top-end power potential.
Maintains a balance between performance and emissions considerations. Significantly reduces restriction compared to OEM while preserving a more refined exhaust tone.
Integrated thermal shielding reduces engine bay heat transfer. Power output remains unchanged but improves long-term component protection.
Compared to Stage 1 configuration:
• +32–77 HP increase
• +41–84 lb-ft additional torque
• Substantially stronger mid-range acceleration
• Improved high-RPM pull
For the 4.0T EA824 platform, downpipes are the defining hardware requirement for full Stage 2 performance capability.
The twin-turbo 4.0T generates significant charge heat under aggressive driving. The factory cooling system can become heat-soaked during repeated acceleration or high-speed operation, reducing ignition timing and power consistency.
Upgrading the intercooler ensures stable intake air temperatures and preserves full ignition advance under load.
Wagner Tuning Performance Intercooler System
Wagner Tuning intercoolers are engineered with high-density bar-and-plate cores designed to significantly increase cooling surface area while minimizing pressure drop. Precision end tank design ensures even airflow distribution across the core, optimizing charge-air cooling efficiency under high boost conditions.
These systems are specifically developed for the Audi 4.0T platform and are tested for durability under sustained thermal load.
• Maintains peak horsepower during repeated acceleration
• Dramatically reduces heat soak
• Stabilizes boost pressure under high load
• Supports full Stage 2 and higher torque output
Intercooler upgrades do not independently increase peak horsepower but are critical for maintaining performance consistency — especially in heavier executive chassis platforms and high-speed driving conditions.
The ECU calibration unlocks the true capability of the 4.0T EA824 platform by coordinating airflow upgrades with refined boost control and torque mapping.
