Porsche Performance Intake Plenum For Porsche 996 Carrera (1999-2004) Models.

IPD Competition Plenum:

• Designed for Modified Cars: Optimized for vehicles with performance exhaust systems.
• Larger Throttle Body Upgrade: Utilizes Porsche's next largest throttle body size (82mm 997 GT3 throttle body for Carrera models, replacing the 74mm OE).
• Enhanced Laminar Flow: Features an innovative internal merge collector area for improved airflow.
• More Linear Power Delivery: Provides a smoother and more consistent power curve.
• Improved Throttle Response: Enhances the responsiveness of the engine.
• Noticeable and Impressive Gains: Delivers significant power increases.
• ECU Adaptation Required: Power improvements are fully realized after the ECU/DME adapts through hard pulls.
• Professional Installation Recommended: IPD strongly suggests installation by a trained Porsche technician.

IPD Plenum Features & Benefits:

• Superior "Y" Design: More efficient than the factory intake, improving airflow and increasing air velocity.
• Dimpled Interior Surface: Creates more laminar (less turbulent) airflow.
• Across-the-Board Power and Torque Gains: Improves power and torque throughout the entire RPM band.
• Effective with Any Modification Level: Delivers impressive gains on both stock and highly modified Porsches.
• Outperforms Factory Intake: The IPD Plenum's efficient design will always outperform the factory air distributor, especially with increased power output.
• Substantial Gains for NA and Turbo: Provides considerable power increases for both naturally aspirated and turbocharged engines.
• Similar Percentage Gains: Achieves almost identical percentage gains (around 8-10%) for different models.
• No ECU Flash Required: Does not necessitate an ECU re-flash after installation.
• No CEL Issues: Should not cause a Check Engine Light (CEL) if installed correctly.
• Aluminum Construction: Aluminum Plenums run cooler and do not suffer from heat soak due to aluminum's superior thermal conductivity and heat capacity compared to plastic.
  • Aluminum is 650 times more thermally conductive than plastic.
  • Aluminum has a specific heat capacity 550 times higher than plastic.
• OEM Aluminum Intake Precedent: Porsche utilizes aluminum intakes on high-performance models like GT3, GT2, Cup Cars, and Cup R's.
