I purchased the Plenum and GT3 Throttle body for my 2004 911 what a huge difference this combination has made, Much more Responsive Acceleration and Pull, which equals even more Fun to drive, especially with a 6 speed Manual Transmission.

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!

This upgrade is an easy way to gain horsepower for an affordable price!
I wish I would have done it earlier!

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.

Installed IPD plenum and GT3 throttle body for my 2007 911 4S. I also ordered a software Flash for my ECM. The support team with IPD were very helpful communicating with my Indy mechanic in getting the software installed. I cannot believe the additional power gained. Thanks IPD!!

I purchased a plenum from IPD in July 2022, the 84 mm enlarged plenum. I experienced an instant boost in horsepower accompanied by an incredible howl when I opened the throttle at about 3000 rpm.

The car was already fast, now it is absolutely insane when accelerating from 60 to 100 mph and beyond. I highly recommend IPDs plenums, installation was relatively easy and the parts are of high quality.

IPD needs to start making exhausts and other parts that increase HP!!
