The incredible 991 Porsche Turbo received a completely redesigned exterior but the engine remained virtually identical to the previous model 997.2 Turbo. This latest Turbo is the most powerful, revolutionary and capable Porsche Turbo to ever come out of Stuttgart. This latest generation Turbo engine, titled the 9A1, delivers 520 HP (560 HP with the "S") and once again, raises the proverbial performance bar in the sports car world.
The new 991 IPD Turbo Plenum is nearly identical to the previous 997.2 Turbo Plenums. The new IPD Turbo Plenum is offered in one single 74mm version which utilizes the factory 74mm throttle body. The 991 Turbo intake manifolds are smaller than the 997.1 Turbo manifolds which is great for improved boost response and gas mileage but less than ideal for making substantial power gains. The 74mm TB provides more than adequate flow for these more restrictive intake runners eliminating the need for a larger 82mm "Competition" version.
The already explosive power of the 991 Turbo can be further increased with the new 991 Turbo IPD Intake Plenum. The patented IPD Plenum design works exceptionally well with all forced induction applications and the 991 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay well above all factory power curves from launch to redline. Maximum power increases take place in the midrange where it's most needed, most critical and most enjoyed.
The 991 Turbo plenums deliver smooth and linear power with considerably quicker boost response creating a longer and more desirable power band. The Turbo plenums deliver reliable performance for both street and motorsport applications enhancing the already visceral Porsche Turbo driving experience.
The 991 Turbo requires an "adaptation" period that can be fully realized with either a series of hard pulls on the dyno or a series of spirited driving sessions, which of course IPD recommends only be performed on a closed course circuit. Installation of all Turbo Plenums is highly recommended to be performed by qualified and trained Porsche technicians.
Seeing this is not the turbo forum, any info on non turbo models??
Also, the pieces look similar except plastic vs. aluminum. Curious on how these gains are truly realized.
Plus install time in hours?
In non turbo news:
Fabspeed Competition Intake! Fabspeed’s Maxflo Competition Intake
Fabspeed’s Maxflo Competition Intake system improves the induction into the engine increasing power throughout the RPM range.
Features carbon fiber Y-pipe with dual-conical performance air filters.
Direct replacement for restrictive OEM airbox and paper filters.
Requires removal of rear bumper for installation.
Emission compliant with no Check Engine Light.
Maxflo performance products are backed by the Fabspeed Lifetime Limited Warranty.
I apologize for placing this into the wrong forum, I will repost there as well.
To answer your question, in hours: 3 (With care/no air tools)
And last, Basically: More air + increased airflow along with the adaption of the motor = more horsepower/torque. The IPD Y shape vs the OEM T shape is the main cause of this. Also the "divots" in the manifold help create a smooth surface to keep airflow moving faster, just like on a golf ball, or the bed of a pickup truck.

I'm interested in upgrading suspension and performance on a 991 C2S. Any recommendations and what horsepower/torque gains can one expect?
Sorry to bring back an old thread but curious regarding difficulty in accessing and removing the plenum on a 2017 911.2 Turbo S. Looks like tight quarters especially to get your hands in to twist the couplers. Do you need to drop the engine at all? Im about ready to do a y pipe and am considering the plenum as well but I want to make sure it’s worth it relative to the effort.
P.S. - open to answers from anyone who has done the install.
I love the quote where he says "The new 991 IPD Turbo Plenum is nearly identical to the previous 997.2 Turbo Plenums" and yet the part used says "997.2 TT" right on it....
