The perfect compliment to Fabspeed's 981 Boxster/Cayman exhaust upgrades, this high performance intake plenum from Innovative Pro Design and upgraded 82mm throttle body provide substantial power gains by increasing the efficiency and flow of the engine's air intake system.                                                                                 

FEATURES:

After a very extensive R&D program, we are proud to launch the new 981 IPD 82mm Competition Plenums specifically designed to work in perfect concert with the upgraded 82mm throttle body. This combination has proven to be extremely effective and deliver even more performance than doing either component on its own. This Competition Plenum package 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 developed a custom silicone hose designed to perfectly fit the larger 82mm throttle body 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 14 horsepower and 12 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.

Superior and more efficient design over the factory intake.

The IPD Plenums are products of efficiency that simply improve intake air flow and increase air velocity. The “Y” shape design and dimpled interior surface make air flow more laminar (less turbulent) dramatically improving power and torque across the entire RPM band. Smoother more optimized intake air flow will improve the performance of any engines. The more efficiently an engine breaths, the more efficiently it produces power. 

 

Deliver impressive power gains regardless of modifications.

The superior design of the IPD Plenums optimize flow while increasing air velocity. Period! This applies to any Porsche engine, producing any level of power. The patented “Y” design delivers impressive performance gains 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 detrimental to performance as your increase the power and torque outputs. The bigger the power, the better the IPD Plenum performs.

Produce substantial gains for both turbo and NA applications.

The Plenums always deliver considerable gains on both turbo AND naturally aspirated engines. It's a fact that the Turbo Plenums do produce more power than the NA Plenums. But the Turbo engines also produce more power. The fact is that the percentage gains of the different Plenum applications are actually almost identical, around 8-10% depending on the specific model. 

Aluminum Plenums run cooler and don't suffer from heat soak.

The Aluminum Plenums do NOT experience heat soak under driving or racing conditions. It is true that aluminum has a higher thermal conductivity than plastic. In fact, aluminum is 650 times more thermally conductive than plastic and has a specific heat capacity that is 550 times higher than plastic. This means the aluminum Plenum actually spreads the energy it's exposed to 656 times faster than the plastic and can store more than 550 times the amount of energy per unit mass. Bottom line, aluminum can absorb more heat than plastic, but it also takes considerably more energy to heat up and it's losing that energy way faster than the aluminum allowing the IPD Plenum to remain cooler from outside ambient air under driving conditions, ultimately improving engine performance over plastic. Plus, why would Porsche utilize aluminum intakes on GT3's, GT2's, Cup Cars and Cup R's?

ECU Performance Software recommended.

The 981's are likely, but not guaranteed, to experience a CEL related to increased air-flow after installing the IPD Plenum and larger 82mm GT3 Throttle Body. Unlike previous generation Porsches that used a MAF (Mass Air Flow) style metering device, the new 981's employ a MAP (Manifold Absolute Pressure) sensor based intake system.  As a result, the factory air flow tables are much more stringent (lower), and the ECU is much more discerning of additional air being introduced into the intact tract. 
Assuming the installation was performed perfectly, it seems that about half of all 981 applications (Non-S, S, GTS, Spyder and GT4) will still require a throttle body adaptation after installing of the IPD Plenum and 82mm GT3 TB. This procedure can ONLY be performed with a factory Porsche PIWIS computer. Once the TB adaptation has been performed, you “should” be CEL free. 
 
But occasionally some of the 981 applications will continue to experience a CEL related to the ECU reading intake air flow levels that exceed the threshold values programmed within the firmware of the ECU, ultimately causing one of the following fault codes (P0068, P1095 or P1074). If a CEL continues, we strongly suggest a revised mapping of the ECU or have a qualified Porsche ECU tuner to either disable or isolate and raise the air flow levels within the tables of the ECU to complement the IPD Competition Plenum, larger TB and additional intake air flow being delivered by the IPD upgrade. 
 
Note: These CEL's do NOT affect performance or reliability of any 981, it's just the ECU letting you know that the intake tract is flowing more air than the car is programmed to receive, which is exactly what the IPD Plenum is designed to accomplish. This is how the performance gains are being realized.

These pillows perform wonderfully and they hold up!
Color: Grey, Size: Standard, Color: Grey, Size: Standard
I have had these pillows for 5 years, so mine is not in brand new condition in this photo but they still appear pretty good and function wonderfully. I recommend these to others looking for a soft but supportive pillow. They are the standard microfiber cooling ones. I have one and my daughter (7) has the other. We use them every night and they are just the perfect amount of medium-softness for both of us despite us being very different in size! Still fluff back up, have just enough support and height or thickness in my opinion (I don’t like very firm microfiber pillows as much, and I don’t like the feather pillows that aren’t goose down because they get crunchy and flat). Love these pillows, the price is super reasonable for the product they provide. They have held up this long, I’d say they are of good quality. I’ve just ordered another set for a visit to my mothers house! Our favorite pillows!

Super Comfortable and Easy to Sleep On
Color: Memory Pillow, Size: Standard
HIMOON Shredded Memory Foam Pillows are honestly way more comfortable than I expected—they’re soft but still supportive, and I like that I can adjust and fluff them to fit how I sleep. They feel good for both side and back sleeping, and they don’t go flat like some cheaper pillows I’ve tried. After using them for a while, they’ve held up well and still feel cozy every night. Overall, just a really comfortable, no-stress pillow that makes it easy to fall asleep 👍

Good pillows; wear a mask when fluffing and airing out
Color: Memory Pillow, Size: Standard
Searched everywhere for comfortable pillows, finally found this set. Perfect density and firmness, very comfortable. Downside is that they were covered in some type of white powder which dispersed as I was fluffing them up. Fiberglass, maybe? I recommend customers fluff and air them outside before use, and wear a mask. Pillows had an industrial smell, which dissipated after 20 minutes in the fresh air.
