    Product description

    The perfect complement to Fabspeed's GT4 exhaust upgrades, this premium intake plenum from Innovative Pro Design and the upgraded 82mm throttle body provide significant power gains by increasing the efficiency and flow of the engine's air intake system.

    CHARACTERISTICS:

    After a very extensive R&D program, we are proud to launch the new GT4 IPD 82mm Competition Plenums, specially designed to work perfectly with the upgraded 82mm throttle body. This combination has proven to be extremely effective and outperforms any single component.

    The GT4 intake is almost identical to the 987.2 & 981 intake. Porsche has made a few upgrades with the 981 and GT4, notably that the GT4 draws in outside air through both driver and passenger air intakes rather than just the driver's side, as previously found in all 986, 987 and 987.2 applications. IPD has developed a custom silicone hose that fits perfectly on the larger 82mm throttle body and significantly improves airflow.

    The new GT4 Plenum also benefits from the internal dimple effect that we now apply to all future plenums. These internal dimples allow us to control the boundary layer and maximize airflow. Just like a dimpled golf ball travels further than a smooth golf ball. Controlled turbulent air creates less friction and "tumbles" more efficiently over a specific area.

    The power gain with the GT4 Competition Plenum is almost the same as with the 981 Competition Plenum, taking 17 horsepower and 11 foot pounds of torque at the wheels. Most of the power gain from the IPD Plenum starts at approximately 4000rpm, continues through to the redline and is fully realized in the 6000rpm range. The performance improvements from IPD remain above both factory power curves throughout the speed range.

    Superior and more efficient design compared to the factory shot.

    The IPD plenums are efficient products that simply improve the intake air flow and increase the air speed. The "Y" shape design and dimples inside make the airflow more laminar (less turbulent), significantly improving power and torque across the entire RPM band. A smoother, more optimized intake airflow will improve the performance of all engines. The more efficiently a motor breathes, the more efficiently it produces power.

    Deliver impressive capital gains regardless of changes.

    The superior design of the IPD plenums optimize the flow and increase the air speed. Period! This applies to any Porsche engine that produces any power level. The patented "Y" design delivers impressive performance improvements for both bone-stock and highly modified Porsches. The more efficient design of the IPD Plenum will always outperform the factory air distributor. The factory intake will become even more damaging to performance as you increase power and torque. The greater the power, the better the IPD Plenum performs.

    Realize significant profits for both turbo and NA applications.

    The plenums always provide significant benefits for both turbo and naturally aspirated engines. The fact is that the Turbo Plenums produce more power than the NA Plenums. But the turbo engines also produce more power. The fact is that the percentage gain of the different Plenum applications is actually almost identical, about 8-10%, depending on the specific model.

    Aluminum plenums become cooler and are not affected by heat radiation.

    The aluminum plenums do NOT experience any heat build-up under driving or racing conditions. It is true that aluminum has a higher thermal conductivity than plastic. In fact, aluminum is 650 times more heat-conducting than plastic and has a specific heat capacity 550 times higher than plastic. This means that the Aluminum Plenum spreads the energy it is exposed to 656 times faster than the plastic and can store more than 550 times the amount of energy per unit mass. In short, aluminum can absorb more heat than plastic, but it also takes significantly more energy to heat up and it loses that energy much faster than the aluminum, keeping the IPD Plenum cooler from the outside air under driving conditions, ultimately improving engine performance. about plastic. And why would Porsche use aluminum intakes on GT3s, GT2s, Cup Cars and Cup Rs?

    ECU Performance Software recommended.

    The 981s are likely, but not guaranteed, to experience a CEL due to increased airflow after installing the IPD plenum and the larger 82mm GT3 throttle body. Unlike the previous generation Porsches that used a MAF (Mass Air Flow) measuring device, the new 981s use a MAP (Manifold Absolute Pressure) sensor-based intake system. As a result, the factory air flow tables are much stricter (lower) and the ECU is much better able to bring additional air into the intact duct.

    Assuming the installation was done perfectly, it seems that about half of all 981 applications (non-S, S, GTS, Spyder and GT4) still require a throttle body adjustment after installing the IPD Plenum and 82 mm GT3 TB. This procedure can ONLY be performed with a Porsche PIWIS factory computer. Once the TB fitting is done, you should be "CELL" free.

    But from time to time some of the 981 applications will continue to experience a CEL related to the ECU reading the intake airflow levels exceeding the thresholds programmed in the ECU firmware, eventually causing one of the following error codes (P0068, P1095 or P1074). If a CEL goes through, we strongly recommend that you review the ECU or have a qualified Porsche ECU tuner to disable or isolate and increase the airflow levels in the ECU tables in addition to the IPD Competition Plenum, larger TB and additional intake airflow provided by the IPD upgrade.

    Note: These CELs DO NOT affect the performance or reliability of a 981, it is just the ECU that lets you know that the intake duct is flowing more air than the car is programmed for, which is exactly what the IPD Plenum is designed to reach. This is how the performance gains are realized.
