+ Detailed Product Description

Porsche Cayman 987 IPD Plenum for 2.7L, 3.2L & 3.4L Normally Aspirated Engines
  • All aluminum intake plenum replaces factory plastic T design
  • Improves air flow and reduces intake air flow turbulence
  • Consistent gains of 13 HP throughout rpm range
  • Consistent gains of 13 Ft Lbs torque throughout rpm range
  • High flow Y style innovative and patented design
  • Standard size and competition version
  • Easy install, no CEL & perfect fit
  • Optional increased size throttle body

The IPD Plenums upgrade for the Porsche Cayman 987 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 different versions based on the engine type fitted to your Cayman 987. The later engines came with the reusable 74mm throttle body. Early versions require the upgrade. There is also a competition model that requires a 82mm throttle body upgrade:

987 Cayman 2.7L or 3.4L IPD Plenum Competition Version – $795.00

ipd plenum upgrade for porsche cayman 987 completeThe IPD Plenum Competition Version for the 2.7L or 3.4L 987 engine delivers even more impressive horsepower gains than the standard versions shown below. 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 987.

The competition version is larger in diameter at 82mm versus the factory intake of 74mm. This requires the use of an 82mm throttle body used on the GT3 cars and is designed to deliver additional air volume through the intake. Ideally, the IPD Competition Plenum and throttle body upgrade should be combined with other modifications such as intake systems and high flow exhausts for maximum results. The IPD Competition Plenum and throttle body combination help to optimize the power gains made through other modifications.

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 987.

Early 2.7L and 3.2L engine Caymans require an upgraded 74mm throttle body.

+ Our Opinion

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. The competition 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.

+ Installation

Installation is pretty straight forward on the 987 if it does take some leaning in to the engine bay! With some patience and a little shuffling of rubber connectors, the installation doesn’t take long. Always take a good look at the seal on the throttle body, if you plan to re-use it, to make sure it’s in good shape before re-attaching. 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 Porsche specialist shop who can install this for you – or contact us and we’ll recommend a friendly local specialist for you.
