The IPD Plenums upgrade for the Porsche 911 Turbo 997 is an innovative “Y” style designed aluminum intake plenum that replaces the factory plastic T style plenum. The IPD design improves performance by channeling intake air to the cylinder banks more efficiently. This design reduces air flow turbulence caused by the T style design and increases air flow velocity. This results in substantial measurable power gains throughout the entire rpm band and the torque increases are most noticeable at lower rpm.
There are two versions of the plenum and a Y-pipe option based on the modification goals for your 997 Turbo:
997 911 Turbo 74mm IPD Plenum – $950.00
The 74mm IPD Plenum for the 997 Turbo delivers an impressive 45 horsepower peak gain and 35 Ft Lbs torque gain. These gains are mainly felt in the mid to higher end rpm, however, performance improvements are realized throughout the entire rev range. The added power creates a more liner power curve and helps to increase boost response from the turbos. The 74mm plenum reuses the factory throttle body.
This version of the IPD Plenum is designed for cars with basic modifications and not super lofty HP gains. Modifications such as an exhaust, intake etc are well suited to this plenum.
997 911 Turbo 82mm IPD Plenum – $950.00
For modifications designed to enhance the 997 Turbo to above 700 HP the IPD 82mm Competition Plenum and Throttle Body are more suited. The Competition Plenum is widely used in conjunction with ECU software, larger turbos, inter-coolers etc. The additional larger throttle body has helped the plenum to deliver on horse power targets of 1000 and above on highly modified cars. The 82mm plenum requires the use of a GT3 82mm throttle body.
997 911 Turbo Y-Pipe – $950.00
The IPD 997 Turbo Y-Pipe was re-design from scratch to deliver more air then the factory pipe.
The factory Y pipe can become restrictive when adding larger turbos. The IPD Y-Pipe has larger inlets and an optimized diversion area allowing for greater power gains. This superior design is significantly more efficient and flows 126 cfm more than the factory Y pipe.
IPD was careful to design the Y-Pipe to deliver optimum flow without being too large. Just increasing the pipe size can cause a loss in boost response. These Y-Pipes can also be special ordered in custom powder coated colors and ceramic coatings or polished to improve the aesthetic appeal of your Turbo engine if desired.

+ Our Opinion
The IPD Plenum upgrade is one of a few products that consistently delivers power and torque gains. You can feel the extra torque available and the increased turbo spool in lower speed third gear pulls. The competition plenum, throttle body and Y-Pipe combination enable you to take full advantage of any other engine modifications you might make. Combined with an exhaust, ECU tune and intake, the IPD Plenums definitely deliver results we’ve enjoyed over the years. If your going big on HP numbers, the competition version is the way to go.
Installation requires some more advanced skills. On the 997 turbo there isn’t too much room to work with around the throttle body and factory plenum area. We recommend you seek the assistance of someone who has previous experience of removing the plenum on the turbo before you tackle this one. The Y-Pipe installation in comparison is very simple.
If you’re not comfortable with installing the plenum yourself, we’d suggest you search our directory for a local specialist Porsche shop who can install this for you – or contact us and we’ll recommend a friendly local specialist for you.
