The Best Bolt on Performance Upgrades for Late Model Porsches

IPD logo

Installed IPD plenum and GT3 throttle body for my 2007 911 4S. I also ordered a software Flash for my ECM. The support team with IPD were very helpful communicating with my Indy mechanic in getting the software installed. I cannot believe the additional power gained. Thanks IPD!!

I purchased a plenum from IPD in July 2022, the 84 mm enlarged plenum. I experienced an instant boost in horsepower accompanied by an incredible howl when I opened the throttle at about 3000 rpm.

The car was already fast, now it is absolutely insane when accelerating from 60 to 100 mph and beyond. I highly recommend IPDs plenums, installation was relatively easy and the parts are of high quality.

IPD needs to start making exhausts and other parts that increase HP!!

Installed in my 2011 911S In addition to Carbon Air intake and upgraded Exhaust each upgrade was done separately the latest upgrade the plenum , provided noticeable power and performance enhancement at takeoff Feels like the Sport mode is engaged w/o pressing the button. Highly recommend.

"...The extra torque can definitely be felt especially when getting on it to get on the freeway. Overall I'm happy with the build quality and performance upgrade."

I installed the IPD Plenum and GT3 Throttle Body on my 981 Cayman. The installation was relatively straight forward and was certainly made easier by the use of a slightly longer bolt to pull up the intake clamps. (Once the clamps were pulled tight the original bolts could be reinstalled).
At the same time I also fitted aFe air filters and a Cobb Stage 1 tune. (On initial start-up the engine displayed an error code, the installation of the Cobb tune took care of that problem).
I was pretty sure that there was a performance improvement but the street is not really the place to test this out. However this was reinforced at the track this weekend. Previously the engine really didn't want to pull much over 6,000-6,500 revs, now if feels like it is continuing to produce all the way to the red line. The throttle response is also much more immediate. I am very impressed!
The Soul Exhaust and a Stage 2 Tune is coming soon so I am hoping for further improvements.

Excellent quality and a very straightforward install! I love that this is a thick, cast piece that gives me confidence for similar resilience and longevity to OEM parts, but with higher performance!

I have to say I definitely feel a difference in the torque and HP after installing the competition plenum on my 911. Very quick and easy to install. Definitely ately a must do upgrade !

After taking stock throttle body and plenum off the Porsche and then installed the IPD plenum with new throttle body and silicone hose got more horsepower out of the engine big win I would think reasonable price too

The IPD made all the other performance mods in my car come together. Wow! Transformational. The smoothness and torque through the entire rpm band is addicting. Cannot get enough driving time on my 991.2 Carrera S.
