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.
"...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 run IPD plenum in both my cars, easiest way to get performance gains noticeable by the seat of your pants. Easy install, instantaneous upgrade. Must have parts.
