Description
Competition Intake Plenum For Porsche 997.1 (3.6/3.8L) (2005-2008) Models.
The IPD “Competition” Intake Plenum is a high-performance upgrade designed for Porsche 997.1 Carreras that are already moderately to heavily modified. Porsche has a long history of restricting engine output with smaller throttle bodies, and this plenum is engineered to overcome that limitation.
This “Competition” model is specifically designed to work in conjunction with an upgraded 82mm Porsche GT3 throttle body (required and sold separately), replacing the factory 74mm throttle body. This larger diameter allows the engine to inhale more air, especially when paired with a high-performance exhaust system. The more extensive the exhaust system (headers, catalytic converters, and mufflers), the more effective the plenum’s performance.
IPD has pioneered a new design with the Competition Carrera Plenum, featuring a unique and innovative internal merge collector area. This advanced design significantly enhances laminar flows and volumetric efficiencies, resulting in not only impressive power gains but also a more linear power delivery and improved throttle response.
Key Features:
-
Throttle Body Requirement: Requires an upgraded 82mm Porsche Throttle Body (Additional Charge).
-
Advanced Design: Features a unique internal merge collector for enhanced laminar flows and volumetric efficiencies.
-
Performance Focus: Designed to work optimally with high-performance exhaust systems for maximum power and torque.
-
Performance Gains: Delivers noticeable and impressive gains, though exact figures will vary depending on existing modifications.
-
ECU Adaptation: Full power improvements are realized once the factory ECU/DME completes its necessary “adaptation.” This can be expedited with spirited, full-throttle runs on a closed course.
-
Compatibility: Fits all Porsche 997.1 Carreras (3.6L and 3.8L).
