Intake

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).

IPD Competition Plenum for Porsche 981 Spyder/GT4 Once again, Porsche left the door open for engine performance improvements with the 981 Boxster Spyder and Cayman GT4. Using the same factory intake found on the less-powerful 981 S and GTS models, despite using the 911 Carrera S 3.8L engine, the intake's 74mm throttle body limits power and torque to keep the 981 from treading too close to the 911. As a result, Porsche's 991 Carrera S delivers 420 HP while the GT4 makes 385 HP with the same engine. Why does the GT4 produce 35 fewer horses? (The GT4 engine is only 15 HP stronger than the base Carrera 3.4L engine!) The Carrera S engine, with its 82mm throttle body, benefits from the IPD Plenum, so it figures the GT4 would really benefit from an IPD Competition Plenum and 82mm throttle body. Initial dyno tests performed in Germany showed gains of 18 HP and 17 lbs-ft. of torque at the GT4's wheels. Considering that the 981's ECU requires more adaptation time than other Porsche models (over a hundred miles for the full adaptive process), this means the full performance gains for the GT4 will be even greater. Competition Motorsport installed the IPD Competition Plenum and 82mm TB on our GT4 and were immediately impressed with the increased mid-range and top-end power and torque, and throttle response. The IPD plenum delivers net gains throughout both power and torque curves, helping the GT4 compete with its GT3 big brother. 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 981 (2.7L) This plenum requires a Bosch 82mm throttle body, which can be added to your order above for only $225 (save $100). The product of an extensive R&D program, IPD's 82mm Competition Plenum delivers excellent performance and value. The Competition Plenum upgrades the factory 74mm throttle body to the larger 997 GT3 82mm throttle body. This combination has proven to be the most popular and deliver even more performance. Porsche made a few upgrades to the 981 intake versus the 987; most notably, the 981 draws outside air from both driver- and passenger-side air intakes instead of the driver-side only. IPD developed a custom silicone hose designed to perfectly fit the larger 82mm TB and considerably improve air flow. Their 981 plenum also benefits from the internal dimpling effect they've implemented on all plenums. This internal dimpling allows IPD to control the boundary layer and maximize air flow within the plenum. Just like a dimpled golf ball travels farther, controlled turbulent air creates less friction and "tumbles" over a given area more efficiently. Power gains with the IPD 981 Competition Plenum are +20 HP and +16 lbs-ft. of torque at the wheels. The bulk of the power gains from the IPD plenum begin at 4000 RPM, become fully realized at 6000 RPM, and continue all the way to redline. IPD performance gains stay above factory power and torque curves throughout the entire rev range.

IPD Intake Y-Pipe for Porsche 997.2 Turbo/Turbo S The revolutionary 997.2 Turbo IPD Y-Pipe was built for the most demanding Turbo performance customer. This is not a cast reproduction of the factory Y-pipe; it is a complete re-design from scratch, developed to deliver greater air flow for both stock and highly-modified Porsche 997.2 Turbo or Turbo S engines. The factory Y-pipe becomes restrictive when adding substantial power gains, particularly when you increase boost. The IPD Y-Pipe has larger inlets and a dimpled flow-optimized diversion area, removing the restrictions of the stock pipe. This superior more efficient design flows 126 CFM more than the factory Y-pipe delivering the additional capacity needed to raise the performance bar on the 997.2 Turbos. Bigger isn't always better, and the IPD Y-Pipe is designed to deliver optimum flow without being so large as to cause a loss in boost response. The IPD 997.2 Turbo Y-Pipe is designed to be a direct replacement of the factory OEM Y-Pipe. There are no modifications or fabrication required for installing the IPD Y-Pipe. This is an easy and straight forward bolt-on upgrade.

IPD Intake Y-Pipe for Porsche 991.1 Turbo/Turbo S The 991.1 (2014-16) 911 Turbo and Turbo S from Stuttgart offer ballistic acceleration and top speeds on either side of 200 mph. Of course, there's always room for performance improvement for Porsche driving enthusiasts looking to raise the performance bar even higher. IPD invested countless hours of R&D with a variety of unique design features and testing multiple prototypes before settling on the optimum design to significantly improve engine performance for both stock and highly modified 991.1 Turbos. Their innovative Y-Pipe design is not only larger but also utilizes “non-round” runners, an optimized merge collector area, and their proven dimpled interior surfacing. This superior design delivers greater volume of air, improved laminar flow, and increased air velocity, delivering an additional 35 horsepower and 40 lbs-ft of torque at the wheels! Plus improved boost response and more linear horsepower and torque curves. As you know, bigger is not always better when it comes to forced induction applications. The IPD Y-Pipe is considerably larger than the factory, but not so large as to cause pressure drop within the intake tract that could result in turbo lag and reduced performance. This optimized “non-round” design with dimpled interior surface cannot be achieved with conventional round tube construction. The 991.1 Turbo/Turbo S Y-Pipe is a direct bolt-on engine upgrade that requires no modifications but should be perform by an experienced Porsche technician familiar with the 991.1 platform. IPD Y-Pipe comes with all the required hardware necessary to complete the installation.

IPD Intake Plenum for Porsche 997.2 Turbo/Turbo S The incredible 997.2 Porsche Turbo and Turbo S received a completely redesigned engine with many substantial upgrades. At the time, they were the most powerful, revolutionary, and capable Porsche Turbos ever to come out of Stuttgart. The 997.2 Porsche Turbo may have been labeled a "facelift" but the engine was a major evolutionary leap forward in Porsche's coveted Turbo history. This seventh-generation Turbo engine, titled the 9A1, delivers 500 HP (530 HP in the "S") in stock trim. The 997.2 IPD Turbo plenum was considerably more difficult to design and develop than previous plenums. The good news is that all these efforts yielded a much easier installation process than previous Turbo plenums. The IPD 997.2 Turbo plenum is offered in a single version that utilizes the factory 74mm throttle body. The 997.2 Turbo intake manifolds are smaller than the 997.1 Turbo manifolds, which is great for improved boost response and gas mileage but less than ideal for making substantial power gains. The 74mm TB provides more than adequate flow for these more restrictive intake runners eliminating the need for a larger 82mm Competition version. The already explosive power of the 997.2 Turbo can be further increased with the new 997.2 Turbo IPD intake plenum. The patented IPD plenum design works exceptionally well with all forced induction applications, and the 997.2 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay well above all factory power curves from launch to redline. Maximum power increases take place in the midrange where it's most needed and most enjoyed. The IPD 997.2 Turbo Plenum delivers smooth, linear power with considerably quicker boost response creating a broader, more desirable power band. The Turbo plenum gives reliable performance for both street and motorsport applications, enhancing the already visceral Porsche Turbo driving experience. Porsche's 997.2 Turbo ECU requires an adaptation period that can be fully realized with either a series of hard pulls on the dyno or a series of spirited driving sessions (which, of course, IPD recommends only be performed on a closed course circuit). Installation of all Turbo Plenums is highly recommended to be performed by qualified and trained Porsche technicians.

This latest Turbo is the most powerful, revolutionary and capable Porsche Turbo to ever come out of Stuttgart. This latest generation Turbo engine, titled the 9A1, delivers 520 HP (560 HP with the "S") and once again, raises the proverbial performance bar in the sports car world. The new 991 IPD Turbo Plenum is nearly identical to the previous 997.2 Turbo Plenums. The new IPD Turbo Plenum is offered in one single 74mm version which utilizes the factory 74mm throttle body. The 991 Turbo intake manifolds are smaller than the 997.1 Turbo manifolds which is great for improved boost response and gas mileage but less than ideal for making substantial power gains. The 74mm TB provides more than adequate flow for these more restrictive intake runners eliminating the need for a larger 82mm "Competition" version. The already explosive power of the 991 Turbo can be further increased with the new 991 Turbo IPD Intake Plenum. The patented IPD Plenum design works exceptionally well with all forced induction applications and the 991 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay well above all factory power curves from launch to redline. Maximum power increases take place in the midrange where it's most needed, most critical and most enjoyed. The 991 Turbo plenums deliver smooth and linear power with considerably quicker boost response creating a longer and more desirable power band. The Turbo plenums deliver reliable performance for both street and motorsport applications enhancing the already visceral Porsche Turbo driving experience. The 991 Turbo requires an "adaptation" period that can be fully realized with either a series of hard pulls on the dyno or a series of spirited driving sessions, which of course IPD recommends only be performed on a closed course circuit. We recommend nstallation of all Turbo Plenums be performed by qualified and trained Porsche technicians.
