IPD Competiton Plenum for Porsche 987.2 DFI Boxster/Cayman Porsche's DFI (Direct Fuel Injection) intake in the 987.2 Boxster/Cayman (2009-2012) was a totally and completely redesigned intake system developed to improve performance, fuel consumption and emissions by optimizing the air fuel mixture directly inside the combustion chamber. The DFI Porsche engine package is a finely-tuned performance machine and additional power proved difficult to find. The unique design of Porsche's new DFI intake system posed very challenging tuning hurdles. As usual, however, Porsche left the door open for engine performance improvements with the 987.2 Boxster and Cayman. Porsche is famous for controlling Boxster and Cayman engine output by choking the inlet tract with a less-than-optimum throttle body. This has handicapped the smaller Porsches from treading on 911 Carrera territory. Once again, IPD developed a design that out-performs the factory intake system without compromising reliability and drive-ability, bringing the Cayman and Boxster much closer to the performance of the 911! This innovative and revolutionary IPD DFI Intake Plenum employs the patented "Y" design as well as an enlarged plenum area that allows for improved intake air speed and air velocity resulting in performance increases without any power losses. This plenum requires a Bosch 82mm throttle body, which can be added to your order above for only $225 (save $100).

IPD Competition Plenum for Porsche 997.1 Carrera/Carrera S The IPD "Y" design plenum replaces the factory "T" style air distributor and provides substantial power and torque gains by means of a more efficient design. 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 useable and enjoyed. The IPD plenum not only delivers impressive power and torque increases but also creates a more linear power and torque band. Tiptronic customers even claim considerable improvements with more positive shifting after installing the IPD Plenums. Porsche has been controlling engine output by restricting the inlet track for decades. This has been successfully accomplished by utilizing smaller throttle bodies. This simple power control solution has been a very effective way of preventing lower level models from out performing certain flagship models, especially models with prolific racing pedigree. Although the factory engine packages are fantastic performance machines, they are engineered and developed to achieve specific performance numbers that satisfy a target demographic and compete with rival brands. Unfortunately driving enthusiasts who seek an elevated Porsche driving experience require performance levels well outside the target market. 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 Plenum does away with your original 74mm throttle body in favor of Porsche's 82mm 997 GT3 throttle body (can be added above). All of our Competition Plenums are designed to perform with cars equipped with high performance exhaust systems. The more extensive the exhaust system (headers, kats 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 efficiencies have 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. This plenum requires a Bosch 82mm throttle body, which can be added to your order above for only $225 (save $100).
