Aluminum intake plenum kit. Porsche 981 DFI Cayman Spyder/GT4 (3.8L)
Code: IPDKIT81482-38
Aluminum Intake Plenum kit.
Includes 82mm throttle body

Fits:
Porsche 981 DFI Cayman Spyder/GT4 (3.8L)

After a very extensive R & D program we are proud to launch the new 981 IPD 82mm Competition Plenums. We only offer "Competition" versions of the 981 Plenums which upgrades the factory 74mm throttle body with the larger 997 GT3 82mm throttle body. This combination has proven to be considerably more popular and deliver even more performance. This Competition version will work with both 3.4L "S" and 2.7L "Non-S" applications.

The 981 intake is nearly identical to the 987.2 intake. Porsche made a few upgrades with the 981, most notably being that the 981 draws outside air from both driver and passenger air intakes instead of the driver's side only as previously found with all 986, 987 and 987.2 applications. IPD has included a custom silicone hose designed to perfectly fit the larger 82mm TB and considerably improve air flow.

The new 981 Plenums also benefits from the internal dimpling effect that we are now implementing on all future Plenums. This internal dimpling allows us to control the boundary layer and maximize air flow. Just like a dimpled golf ball travels farther than a smooth golf ball. Controlled turbulent air creates less friction and "tumbles" over a given area more efficiently.

Power gains with the 981 Competition Plenum are virtually the same as with the 987.2 Competition Plenum, putting down 20 horsepower and 16 foot pounds of torque at the wheels. The bulk of the power gains from the IPD Plenum begin around 4000 rpm, continues all the way through to redline and become fully realized in the 6000 rpm range. IPD performance gains stay above both factory power curves throughout the entire rev range

987 Competition Cayman 3.2L Plenum: HP Gains 20+ / Torque Gains 18 Requires upgrading factory 68mm Throttle Body with 74mm Throttle Body

Recommended to be installed on modified Caymans with Hi-Flow Cat back exhaust


The perfectly balanced mid engine Cayman/Boxster is Germany's canyon carving track meister. Unfortunately, the Cayman/Boxster was delivered slightly under powered from the factory so as not to threaten the Carrera's thrown. The Cayman IPD intake plenum delivers increased performance that puts the Cayman/Boxster in the ring with the Carrera.

The IPD Plenum out performs every other intake system on the market. Don't be fooled by other competitors claiming to offer Plenums. All factory Porsche air distributors are of the "T" variety and therefore suffer from less than ideal air flow and intake air speed.

The genius and power behind the IPD plenums comes from the patented "Y" style design and optimized diversion areas to deliver real and impressive power that will transform your Cayman's/Boxster's performance and heighten your Porsche driving experience.

The Cayman/Boxster IPD Intake Plenums are available in 3 versions, each one specifically designed to meet the performance requirements of varying Cayman/Boxster enthusiasts. IPD offers the ultimate Cayman/Boxster performance upgrades, all the way from mild to wild.

The IPD Cayman/Boxster "Competition" Plenum was designed to meet the needs of the most demanding Cayman/Boxster S enthusiasts. The "Competition" Plenums is even larger and utilizes the 74mm throttle body allowing it to deliver even greater air flow and substantial increases in performance.

The "Competition" version is designed to work with both bone stock Caymans/Boxsters but produces even more horsepower gains (20+) with Caymans/Boxsters already equipped with after market "cat back" high flow performance exhaust and other performance mods.

Aluminum Intake Plenum. Porsche 987 Cayman/Boxster DFI IPD
Code: 87474
Porsche's new DFI (Direct Fuel Injection) intake is a totally and completely redesigned intake system developed to deliver improved 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 has proved difficult to find. The unique design of Porsche's new DFI intake system posed very challenging tuning hurdles but once again IPD developed a design that out performs the factory intake system without compromising reliability and drive-ability.

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 loses.

The all new specifically designed IPD 3.4L DFI Cayman/Boxster Plenum is a direct bolt-on upgrade that replaces the factory plenum and utilizes all pre-existing factory hardware including the OE factory throttle body.

The improved IPD intake design allows for smoother, less turbulent and more efficient air flow with higher velocity air intake speed creating impressive power and torque gains.

The superior design of the DFI IPD Plenum provides an additional 12-14 horsepower at the wheels. Unlike previous naturally aspirated IPD plenums that delivered stronger gains in the mid range, the new IPD DFI Plenums deliver a similar shaped power curve as the factory but are considerably stronger from the mid range to redline.

Power output in the lower rev range follows the Porsche factory output, with NO loses. Power and torque are realized in the midrange and continue to climb above factory power outputs all the way up to redline.

Installation of the new IPD 3.4L DFI Plenum is relatively straight forward and can be installed by mechanically inclined DIY customers although IPD strongly recommends installation be performed by a trained and qualified Porsche technician.

In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor.

The largest piece inside the throttle body is the throttle plate, which is a butterfly valve that regulates the airflow. Have a larger diameter throttle body produces more air flow with equals more power. The upgrades should be used in conjunction with the competition plenums.

This is a 74mm Throttle body.
