The IPD Plenums upgrade for the Porsche 911 BT3 996 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.
996 911 GT3 82mm IPD Plenum – $850.00
The IPD Plenum for the 996 GT3 delivers an impressive 24 horsepower peak gain and 22 Ft Lbs torque gain. These gains are mainly felt in the higher end rpm, however, performance improvements are realized throughout the entire rev range. The additional power comes on tap above 5K rpm which is ideal for a track based car.
Use of the IPD Plenum does require a throttle body upgrade ($295). IPD recommends the 82mm throttle body from the 997 GT3 to optimize performance.

+ Our Opinion
Increasing the power output from the GT3 engine is no simple task, however, the IPD Plenum upgrade is one of a few products that consistently delivers power and torque gains.
Once installed, you can feel the extra torque available in lower speed third gear pulls. The plenum and throttle body 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 on the track over the years.
Installation is pretty straight forward. On the 996 GT3 there isn’t too much room to work with around the throttle body and factory plenum area. However, with some patience and a little shuffling of rubber connectors, the installation doesn’t take too long. The bolts for the throttle body are soft and easily stripped, so don’t over tighten.
We recommend resetting the fuel mixture adaptions after installing. This allows engine management to relearn the volume of air available and helps to deliver more consistent power gains.
If you’re not comfortable with installing the plenum yourself, we’d recommend you search our directory for a local specialist shop who can install this for you – or contact us and we’ll recommend a friendly local specialist for you.
