991 GT2 RS IPD Plenum & Y-Pipe

The revolutionary and patented design of the IPD Porsche Plenum improves intake air -flow by replacing the factory plastic "T" style design with a more efficient, precision casted aluminum "Y" design. The fundamental purpose of a plenum is to deliver smoother air at a higher velocity with greater efficiency. The IPD Plenums distributes the air -flow more effectively while reducing pressure drop at the throttle body inlet by utilizing a true merge collector and dimpled interior surfacing. To further improve airflow, the innovative IPD High Flow Y-Pipe design is a direct fit OEM replacement that is not only larger but also utilizes “non-round” runners, in addition to the same design principles as the plenum. These improvements of the Y-Pipe alone deliver an additional 35+ wheel HP, 40+ Foot Pounds of Torque. Together, the IPD Plenum & Y-Pipe increase horsepower and torque well above the factory power curve from launch to redline. The result will be smooth and linear power with considerably quicker boost response creating a longer and more desirable power band.


  • Increases horsepower, torque, and boost by responsibly optimizing air -flow efficiency

  • Designed with 3D Modeling & Computational Fluid Dynamics software

  • Utilizes diversion splitter and dimpled interior surface eliminate turbulence and increase air -flow

  • High quality cast aluminum construction

  • Direct fit OEM replacement

  • Made in USA

Cobb Accessport for Porsche 991.2 Turbo / GT2 RS

The Accessport V3 is the world's best selling, most flexible ECU upgrade solution for Porsche. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Upgrade forever with off-the-shelf (OTS) calibrations for most bolt-on modifications. It's the last engine management solution you'll ever need.

Supported Vehicles:

  • 2017-2018 Porsche 911 (991.2) Turbo PDK WM

  • 2017-2018 Porsche 911 (991.2) Turbo S PDK WM

  • 2018 Porsche 911 (991.2) GT2 RS

Cobb Tuning Calibration Notes

There is a new element to the ECU flashing process for vehicles supported by these three Accessports.  Just as COBB did over 10 years ago with it’s first ECU flashes, we will be bringing ECUs in-house in order to unlock them before an Accessport can be installed.  This means the process for installing an Accessport on your 718 or 991.2 vehicles will be a bit more involved than in years past.  Not to fret, we have a system in place to ensure ECUs are shipped and returned in a timely manner.  Customers will be updated at each step along the way, from the initial purchase to receiving the unlocked ECU and Accessport.

2016 Porsche Macan S Stage 2 Power Package Install


We are ready to have some fun with this 2016 Porsche Macan S Stage 2 Power Package Install for Turbo Tuesday!!! The Porsche Macan Stage 2 Power Package includes the COBB Tuning Accessport, AMS Performance Alpha Intercooler System and Alpha Performance Drop in Air Filters. Together, this Stage 2 Upgrade Package increases approximately 20% HP / 48% TQ peak gains & 58% HP/ 59% TQ max gains, depending on conditions and fuel grade.

Macan Stage 2 Power Package

Macan Stage 2 Power Package

The centerpiece of this package is AMS Performance Alpha Macan Intercooler System featuring the highest quality Bar and Plate Garrett Intercooler cores which are a full 43% thicker than OEM! Alpha’s massive cores give you the most power producing intercooler upgrade on the market. Each of the two super thick 85.5mm Garrett cores provide an optimum fin density of 20 fins per inch for unmatched cooling. Channeling cool air to the intercoolers is vital for optimum performance of any intercooler. The Alpha Performance Porsche Macan Intercooler System features rigid, OEM-quality, carbon fiber ducts designed to mate seamlessly to the intercoolers feeding them cooler ambient air more efficiently than the alternatives. Each organic shaped carbon fiber duct is not only highly functional and designed with performance in mind, they are aesthetically striking as well.

OEM vs AMS Alpha Intercoolers Side by Side Comparison

OEM vs Alpha Performance High-Flow Air Filters Side by Side Comparison

Airflow fed through the upgraded intercoolers is improved with Alpha Performance High-Flow filters. Consisting of a synthetic non-woven multi-layer structure, each Alpha Performance High-Flow filter flows an incredible 640 cubic feet of air a minute. The filtration media is tested using the ISO 5011 Fine Testing Standard to a minimum of 97% efficiency rating. The filter does NOT use oil or chemicals of any kind to aid filtration and will not degrade over time with exposure to varying temperatures and humidity like similar cotton based filters. This creates consistent performance between cleanings over the lifetime of the filter. The filter is easily cleaned by blowing compressed air across the media from the inside out to blow off residual dirt and dust.
