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
Fantastic product, excellent design and met performance expectations.
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.
Have gained noticeable power due to the IPD Plenum and Y-Pipe, would recommend to anybody looking for more than what stock has to offer.
Love it! Also added hi flow air box and filter. Picked up 20+ HP and a noticeable amount or low end grunt. Feels great on the track or bopping around in the hills.
As one of the first new Cayman S owners ( American, living in England, USAF military) I made many modifications including an IPD plenum to the 3.4 engine which improved the overall performance and tractability . The Porsche is a "keeper" and the plenum performs faultlessly to this day!
Fantastic build quality and finish. I was hesitant at first but so glad I did it. It is one of the lower cost upgrades we can add to our car. I love the change in sound and improvement in throttle response. Very easy to install with a few simple tools. I wouldn't hesitate to do it again. You'll be glad you did.
