Competition throttle body and plenum allows for maximum air into the engine, ideal for modified Carreras.
Replaces the stock 74 mm throttle body with a larger 82 mm GT3 version. The larger throttle body connects to a matching-size IPD Plenum which offers a more efficient air delivery. This upgrade is recommended to be installed on vehicles with Hi-Flow Cat back exhaust & other significant power upgrades.
All of the IPD Plenums deliver substantial power and torque gains, but when combined with larger throttle bodies they perform even better. All of the IPD "Competition" Plenums utilize the next largest size throttle body offered by Porsche. In this case, the Competition Carrera upgrades the factory OE 74mm throttle body with Porsche's 82mm 997 GT3 throttle body. IPD Competition Plenums are designed to perform with cars equipped with high performance exhaust systems. The more extensive the exhaust system (headers, cats and mufflers) the better. Optimizing air intake and exhaust together creates a balanced performance package that allows the engine to inhale and exhale more air thus creating more power and torque.
IPD has pioneered another new Plenum design with the Competition Carrera Plenum. Laminar flows and volumetric efficiency has been further enhanced with our unique and innovative internal merge collector area. This completely new approach has yielded not only great performance gains but more linear power delivery and improved throttle response as well. Gains vary depending on pre-existing mods and quality of after-market exhaust installed. As we all "should" know, horsepower and torque become harder to find and typically more expensive as we climb the proverbial performance ladder. That being said, performance components yield different power gains depending on the order they were installed. IPD tests and evaluates all products on bone stock cars, this establishes a level playing field and a better "apples to apples" comparison. The Competition Carrera Plenum however is designed to work with applications that are already moderately to heavily modified. Power gains will vary with each Carrera, but the bottom line is, there will be noticeable and impressive gains that are sure to make any Porsche Carrera driving enthusiast smile.
Power improvements will be fully realized once the factory ECU/DME makes all the necessary "adaptation" requirements. This process can be expedited with a series of "hard pulls" or spirited full throttle acceleration runs through the gears. Of course this should only be performed on a closed course circuit.
Horsepower gains range from 24 to 28 depending on engine displacement and engine condition. These max power gains are experienced in the mid range where is it most usable and enjoyed.
Includes a factory GT3 throttle body, IPD Plenum, hose, and other attachment hardware. Fits 2000-2004 996 Carrera models with drive by wire (egas) throttle body, not compatible with cable operated throttle body.
