IPD Plenum Upgrade for Porsche Boxster 986 2.7L & 3.2L

Porsche Boxster 986 IPD Plenum for 2.7L & 3.2L Normally Aspirated Engines

• All Aluminum Intake Plenum replaces factory plastic T design
• Improves air flow and reduces intake air flow turbulence
• Consistent gains of 15 HP throughout rpm range
• Consistent gains of 17 Ft Lbs torque throughout rpm range
• High flow Y style innovative and patented design
• Easy install, no CEL & perfect fit
• Requires increased size throttle body

The IPD Plenums upgrade for the Porsche Boxster 986 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 two different versions based on the engine type fitted to your Boxster 986 with both requiring a throttle body upgrade:

986 Boxster 3.2L IPD Plenum – $750.00

The IPD Plenum upgrade for the 3.2L Boxster engine delivers impressive horsepower gains. These gains are mainly felt in the mid-range rpm, however, performance improvements are realized throughout the entire rev range. The added power creates a more liner power curve and helps to minimizing the dip in power typically experienced in the normally aspirated 986 engines.

A 74mm throttle body is required in addition to the plenum.

986 Boxster 2.7L IPD Plenum – $750.00

The IPD Plenum upgrade for the 2.7LL Boxster engine delivers the same horsepower gains as the 3.2L. These gains are mainly felt in the mid-range rpm, however, performance improvements are realized throughout the entire rev range. The added power creates a more liner power curve and helps to minimizing the dip in power typically experienced in the normally aspirated 986 engines.

A 74mm throttle body is required in addition to the plenum.

This is one of the best modifications you can make to a Boxster. The IPD Plenum upgrade is one of a few products that consistently delivers power and torque gains. It’s not easy to extract more power from the normally aspirated Porsche engines, however, the IPD Plenum does exactly that. You can feel the extra torque available in lower speed third gear pulls. Combined with an exhaust, ECU tune and intake, the IPD Plenums definitely deliver results.

Installation is pretty straight forward. With some patience and a little shuffling of rubber connectors, the installation doesn’t take 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 Porsche shop who can install this for you – or contact us and we’ll recommend a friendly local specialist for you.
