Look how small the stock Plenum is! It's easy to see how the new plenum can generate such major gains!

Gain 35 Horsepower and 40-45 Torque with this IPD Plenum!

Are you ready for the single best performance mod you will ever do to your Porsche 991 turbo? IPD has developed a way to make 40-45 horsepower with a simple bolt on. This IPD plenum will replace your inefficient T shaped intake manifold for this Y shaped or plenum intake manifold. 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 plenum is simple, it channels air more efficiently and increases air speed ten fold. This IPD plenum is a simple product, but there is nothing short of amazing with the gains you will see and feel!

 

If you can't believe the gains, take a look at the DYNO's below for the official DYNO sheets!!!

Installation

  • Professional installation highly recommended for the Porsche 911 Turbos. Installation for the Turbo 911 Turbos requires anywhere from 2 - 5 hours to install, depending on its location.

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.
