Works great, easy install, thanks.

Got plenum for 05 cayenne turbo, I noticed improvement for performance and mileage.

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.

Made a noticeable difference in mid band performance and part throttle drivability of my 2016 Cayenne turbo. I was skeptical at first but it’s still on the car instead of returning it like I expected to do

Excellent product! Fitment was superb and performance gains were apparent immediately when I stepped on the throttle. Have recommended your products to all my friends.
