About IPD
IPD (Innovative Pro Design) — High-Flow Intake Plenums & Performance Upgrades
IPD (Innovative Pro Design) is a specialist US-based manufacturer best known for its performance intake plenums and Y-pipes engineered for Porsche engines. With a patented “Y”-design, IPD plenums replace the restrictive factory plastic intake distributor with a precision-cast aluminum plenum that optimises airflow, reduces turbulence, and enhances engine breathing — resulting in measurable power and torque gains across the rev range.
Trusted by performance enthusiasts and Porsche tuners worldwide, IPD products are designed, tested, and manufactured in the USA with a strong focus on quality, dyno-proven performance, and a satisfaction guarantee. Whether you’re upgrading a naturally aspirated Carrera or extracting more response from a forced-induction Turbo, IPD offers some of the most effective bolt-on airflow upgrades in the Porsche aftermarket.
At Design911, we supply the full range of genuine IPD intake plenums and Y-pipes, allowing Porsche owners to unlock optimal airflow efficiency, improve throttle response, and elevate overall engine performance.
What Does IPD Manufacture?
IPD focuses on high-flow intake plenums, Y-pipes, and
related airflow components for Porsche engines. Their products feature:
- Patented “Y”-design aluminum plenums that improve airflow efficiency over factory parts
- Turbo Y-pipes designed to reduce turbulence in forced induction applications
- Precision engineering and dyno validation for measurable performance gains
- Components designed specifically for Porsche models — from Boxster/Cayman to 911 and SUV platforms
By replacing the restrictive plastic “T”-style intake with a cast aluminum plenum, IPD components increase air velocity and reduce intake pressure drop for improved engine performance.
Why Choose IPD Products?
IPD intake plenums and Y-pipes are a popular performance
upgrade because they deliver:
- Bolt-on horsepower and torque gains without extensive modification
- Smoother throttle response and improved mid-range power
- Stronger airflow dynamics for both NA and turbocharged
- Porsche engines Dyno-proven results and quality manufacturing
Because airflow is fundamental to engine performance, replacing restrictive factory intake components with high-flow IPD parts lets your engine breathe better — improving the driving experience on road and track alike.
When Should You Consider an IPD Upgrade?
Porsche owners should consider an IPD intake upgrade when
they:
- Want to increase horsepower and torque without internal engine modifications
- Are upgrading other performance systems (exhaust, throttle bodies, ECU tuning)
- Desire better throttle response and airflow balance
- Look to extract more performance from forced induction setups
IPD plenums are especially effective when used with supporting upgrades, and they’re often one of the first recommended modifications for performance-oriented Porsche builds.
At Design911, we stock IPD products that meet the expectations of performance enthusiasts and technical Porsche specialists alike.

Information
The incredible 997 Porsche Turbo is the most revolutionary and capable Porsche Turbo to ever come out of Germany. The already explosive power can be further increased with the new 997 Turbo IPD Intake Plenums.
The patented IPD Plenum design works exceptionally well with all forced induction applications and the 997 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay over and above all factory power curves from launch to redline. Maximum power increases take place in the midrange where it's most needed and most critical.
Maximum horsepower gains range from 30 to 35 depending on vehicle condition and pre-existing mods. The 997 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.
Unlike the 996 Turbo the 997 Turbo requires an "adaptation" period that can be fully realized with either a series of hard pulls on the dyno or 10 to 50 miles of hard driving which of course IPD recommends only be performed on a closed circuit race track.
The 997 Turbo has an extremely sensitive ECU/DME making it prone to external environmental corrections so it is imperative that proper, adequate and consistent cooling be available when you dyno any of the 997 Turbos to get accurate and reliable dyno figures both before and after each test.
Installation of all Turbo Plenums is highly recommended to be performed by qualified and trained Porsche technicians.
Power obsessed Turbo customers looking to push the motorsport envelope a little harder would best benefit from the larger 82mm "Competition" IPD plenum fitted with a factory 997 GT3 82mm Porsche throttle body (additional purchase required).
The larger 82mm intake opening allows for even greater air flow to help optimize the more extreme mods such as larger turbos, intercoolers, Y Pipes and more aggressive software.
This larger version Plenum is also designed to perform with the higher flowing IPD "Y" Pipe.
