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 !
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.
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.
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.
IPD, thank you for developing a cable throttle version plenum for the 3.4l motor. I can state that this plenum does provide an immediate improvement in throttle, and therefore engine, response to inputs. As demonstrated by PCA videos, this product does provide the positive results shown and is felt. Thank you again for your Engineering efforts.
Great product and perfect fitment. Had some power gains, super fun to drive afterwards! I should have done this years ago. Took it on the freeway and it was pulling hard. Shipping time was quick and transaction was easy.
This is the second plenum I've used in a build. Despite all the naysayers on forums, this product delivers. It IS the middle of the pipe, you need to do intake and exhaust for maximum benefit. It produces even more power if you go catless for maximum flow. I use this product in every single build I advise on as well. Pair with Fabspeed exhaust for best results.
The IPD plenum made a huge difference in the performance of my 911. Air flow is less restricted, and power delivery is much smoother. I give this product 5/5 stars, and I recommend it for anyone who wants a great upgrade for a reasonable cost.
I installed the plenum which was extremely simple. I was not sure being I did not change the throttle body how much change I would notice. I was very surprised on the acceleration curve improvements from about 3500 to 6500 rpms.
I also think the car overall ran smoother.
