Intake Plenum "Competition" + Y-Pipe + 82mm Throttle Body Porsche 997 Turbo IPD
Code: IPDKIT997TT1
Aluminum Intake Plenum "Competition" + Y-Pipe + 82mm Throttle Body Porsche 997 Turbo IPD


The incredible 997 Porsche Turbo is the most revolutionary and capable Porsche Turbo to ever come out of Germany. The already explosive power can be further increased with the new 997 Turbo IPD Intake Plenums.

The patented IPD Plenum design works exceptionally well with all forced induction applications and the 997 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay over and above all factory power curves from launch to redline. Maximum power increases take place in the midrange where it's most needed and most critical.

Maximum horsepower gains range from 30 to 35 depending on vehicle condition and pre-existing mods. The 997 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.

Unlike the 996 Turbo the 997 Turbo requires an "adaptation" period that can be fully realized with either a series of hard pulls on the dyno or 10 to 50 miles of hard driving which of course IPD recommends only be performed on a closed circuit race track.

The 997 Turbo has an extremely sensitive ECU/DME making it prone to external environmental corrections so it is imperative that proper, adequate and consistent cooling be available when you dyno any of the 997 Turbos to get accurate and reliable dyno figures both before and after each test.

Installation of all Turbo Plenums is highly recommended to be performed by qualified and trained Porsche technicians.

Power obsessed Turbo customers looking to push the motorsport envelope a little harder would best benefit from the larger 82mm "Competition" IPD plenum fitted with a factory 997 GT3 82mm Porsche throttle body (additional purchase required).

The larger 82mm intake opening allows for even greater air flow to help optimize the more extreme mods such as larger turbos, intercoolers, Y Pipes and more aggressive software.

This larger version Plenum is also designed to perform with the higher flowing IPD "Y" Pipe.

IPD
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.

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.

Induction Kit
Engineered for maximum power and sound. This engineered system eliminates the OEM restrictive airbox and incorporates a high flow cone air filter and sealed fresh air chamber. A cone filter has superior air flow characteristics as compared to flat panel filters. The cone filter better shapes the air as it enters through the filter for smoother straighter more formed air. Next, we have CMC machined a MAF housing to the exact tolerances of the OEM housing for precise MAF reading and NO CHECK ENGINE LIGHTS. In addition, the sealed air chamber sections off the cone air filter from the engine compartment so that it can only draw cool outside air for more power. Finally, the system is injected molded from crosslink polyethylene which has the lowest thermal conductivity rating of any single-layered moldable material available on the market today. This is key in keeping intake temperatures low and increasing power.

Aluminum Intake Plenum "Competition" 82MM + Throttle Body.

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.

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. 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.

The 996 did not mark the beginning of a new Porsche chapter, it marked the beginning of a new Porsche book. The prolific 911 was baptized and emerged water cooled, leaving the legendary air cooled engine to live in Porsche history.

The total and complete redesign of the 911 engine was fitted with the vintage plastic "T" style air distributor that Porsche has used since the early 911 days. This intake system was found on virtually all 911 Carrera's until the arrival of the DFI cars in 2009.

The unique, innovative and patented design of the IPD Plenum employs a "Y" design that improves performance by channeling air left and right to the cylinder banks more efficiently. This design reduces air flow turbulence and increases air flow velocity resulting in substantial power gains throughout the entire rpm band.

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.

Just like the Carrera S, it's difficult to find power for the naturally aspirated 3.4L Carrera, but the IPD Plenum does it better than any other after market mod available. This simple bolt on performance upgrade replaces the factory plastic air distributor with the IPD patented aluminum "Y" style Plenum.

The IPD Plenum delivers impressive horsepower gains of 25 and torque gains of 22 by means of a superior and more efficient design. These gains are mainly felt in the mid range where it is most needed and most enjoyed but performance improvements are realized throughout the entire rev range. Impressive Performance improvements like this will truly transform your Porsche driving experience.

These added power gains in the mid range create a more liner power curve helping to minimizing the dip in power typically experienced in the factory curve resulting in considerable performance improvements.

The 996 Plenum installation is a direct bolt on R & R (remove and reinstall) procedure. Installation is relatively straight forward for mechanically inclined DIY customers although IPD strongly recommends all Plenum installations be performed by a trained and qualified Porsche technician.

To fit:
Porsche 997.1 Turbo models 2007-2009, using an upgrade GT3 82mm throttle body


DO88 are proud to present our newly developed Plenum for the Porsche 997.1 Turbos.

With this extreme high flow Plenum, the performance of your 997 generation 1 will increase! - The results of the final design were very impressive as the do88 Plenum totally outperformed the Porsche OEM Plenum by 34% increased flow when used in combination with a GT3 82mm throttle body at the same pressure drop!

• Available for OEM (74mm) and GT3 (82mm) throttle body
• do88 plenum is Y-shaped for improved air flow.
• High quality casting pipe with CNC-machined connections
• Smooth internal surface for best air flow
• Comes with all necessary accessories for installation

The OEM 997 Turbo plenum is T-shaped which means the air flow from the throttle body abruptly changes direction as it is divided to each side of the intake manifolds. It makes sense to design a plenum with a Y-shape instead of a "direct stop into the wall" T-shape. During the development process of this plenum we spent a lot of time with flow simulations of the internal Y-shape design. We made both flow simulations on our CAD system and real tests on our own SuperFlow SF-1020 flow bench on 3D-printed models. To be able to manufacture this final design we choose to make a 3D freeform designed casting. This construction adds a lot of performance but not so much of extra weight. We designed the outside of the plenum to add as little weight as possible overall.

1. do88 Performance Plenum weight is 0,80 kg (1,76 lb) OEM plastic pipe weight 0,28 kg (0,62 lb) and a competitor's cast performance pipe weighed 1,19kg (2,63 lb).
2. The DO88 plenum flows 34% better for GT3 throttle body and 18% better for OEM throttle body compared with the OEM plenum (see diagram below).

The do88 Performance Plenum is straight bolt on when used with the 82mm OEM Porsche 997 GT3 throttle body, but you can also purchase this plenum together with a CNC-machined adaptor plate that allows you to install it with the oem 74mm OEM Porsche 997.1 Turbo throttle body.

Be aware of that the OEM parts were only designed for the power level the car was built for originally. A power increase may cause your stock plenum to hold back the power of your engine, so even on an engine with a software tune the do88 performance plenum will give a performance increase!

do88 performance plenum comes as a complete package with all parts necessary for installation.

When you order this kit, there is one choice that must be made:

Throttle body size: for OEM 74mm or GT3 82mm.

Please note, their is not any throttle body included in this kit.

Porsche 997 Turbo 2007-09

Adding bolt-on horsepower to the 997 Turbo is a continuous quest by many enthusiasts looking for more power. Reverting back to old tuning technologies, Agency Power has developed a larger throttle body and plenum kit for the Porsche 997 Turbo to gain added performance. The point of a larger throttle body is to get in more air.

The more air you bring in, the more power you make. The 997 Turbo's engine intake system works off pulses, so how that air is diverted to either side of the engine is not as important as the volume incoming. The plenum kit includes an OEM Porsche Cayenne Turbo throttle body (part# 94860511503) which is a direct bolt on and plug in for the electronic throttle control with no modifications needed.

This throttle body has a 77.64mm inner diameter compared to the stock one of 75.64mm. We chose to go with this smaller diameter throttle body to give the car more low end horsepower and torque. If the diameter of the throttle body is to big, it will increase turbo lag and performance gains will only be made at the mid to top end RPM range. Since most 997 Turbo users drive their car on the street and track, we developed this product to substantially increase throttle response and improve "usable" power.

The Agency Power plenum kit is made using high quality 6061 aluminum that has been TIG welded and pressure tested in a T shape to mimic the OEM design. The CNC machined 4 bolt throttle body flange features a groove to accompany a rubber o-ring to ensure a secure and sealed fit with the OEM Porsche Cayenne throttle body. The T plenum features the necessary fittings for stock vacuum hoses and breather lines and includes a 1 way check valve needed. Each T plenum is powder coated gloss black for an OEM look and includes new silicone couplers in black and worm clamps to secure it to the factory intake manifolds. The installation of the plenum requires removal of the factory airbox and Y pipe to access the component.

Installation of the Agency Power plenum kit DOES NOT require the ECU to be flashed. The factory ECU will adjust accordingly to the change in throttle body diameter. However, corresponding mods including an ECU flash will only bring out additional power. As it stands alone, the plenum kit will add a bolt on 20 wheel horsepower to your Porsche 997 Turbo. As tested on a VR700 kit, the plenum added nearly 45 horsepower and 60 ft/lbs of torque. Splitting and diverting the air flow and directing it towards the cylinders at a much higher air speed.

Recommended installation time is approximately 3 hours.

HP Gains: 40-45Bhp. 60 ft/lbs of torque
