It's nice to have IPD on my NA 996 3.6L. I had IPD parts for my 992 Carrera also. You can feel a lot of air go into the filter, get more horsepower.

I definitely feel that extra HP and trq ... Even with the 91 octane fuel... Plan to Dyno this combined with the Cobb 81 Octane SW tune!!!

I didn't have to get a custom tune to take advantage of the plenum improvement

I was a little skeptical of the performance boasts but I was pleasantly surprised.
It was not a head pinning back to your seat kind of upgrade but definitely a noticeable difference
that was worth the price.

Throttle response is much improved. IPD Plenum and 82mm throttle body!

Great product! Easy installation and a noticeably BIG improvement! I wish I would have done this sooner!

It has been years since I purchased and installed my first IPD Plenum, in my first Panamera Turbo S. Since then, I have installed IPD Plenums in all of my Panamera Turbo S’s, and one Cayenne Turbo S. It is a truly excellent invention I appreciate and enjoy them very much whenever I step on the gas to 5000+ RPM. It’s truly Amazing!!!” I wish every company had such pride in their service and products.

This upgrade is an easy way to gain horsepower for an affordable price!

Super happy with the new IPD Plenum the guys over @sharkwerks installed on my 992 carrera! Car feels a lot more stronger higher up in the power ban. Solid bolt-on upgrade.

It Completely changed my GT4. It is now very exciting to drive. Better throttle response, and the sound is fantastic! I highly recommend doing this to your GT4. Next up my Speedster. Can't wait.
