Aluminum Intake Plenum 68mm. Porsche 996 Turbo/S/X50/GT2 IPD

96268

Product Information

The all mighty 996 Turbo may be the perfect Porsche of them all to benefit from the IPD Plenum. Horsepower and torque gains are substantial and immediate (no adaptation required).

ipd

Horsepower improvements range from 30 to 35 and boost response improves considerably making for longer, stronger and of course more pleasurable power curves. The IPD plenum develops horsepower throughout the entire power band, especially where it's needed most, from mid range to top end.

Installation of the 996 Turbo Plenum is very challenging and installation should only be performed by a seasoned and qualified Porsche technician.

The 996 Turbo 68mm version is designed to function with the factory 68mm throttle body that was O.E. on all 996 factory Turbos. The 68mm Plenum delivers similar power as the larger 74mm competition Plenum.

Horsepower gains range from 30 to 35 above the stock power band and initial boost response is improved. The IPD plenum delivers more power and more torque giving the 996 Turbo a stronger mid range and top end.

The 68mm Plenum version is perfect for the Turbo customer looking to improve engine performance on both stock and moderately modified Turbos developing under 700 horsepower.

The IPD 996 Turbo Plenum will truly transform the already impressive Turbo performance. The Plenum should be the first performance upgrade installed on any Turbo. They deliver great power gains on all Turbos whether they are bone stock or highly modified.

996 Turbo/GT2 Plenum: HP Gains 30-40 / Torque Gains 40-45. To be used with factory 68mm Thottle Body

Fits:
Porsche 996 Turbo/S/X50/ GT2

Aluminum Intake Plenum. Porsche 996 C2/4 3.4L 1998-99 IPD (FOR EARLY CABLE THROTTLE CARS)

ipd

The 996 did not mark the beginning of a new Porsche chapter, it marked the beginning of a new Porsche book. The prolific 911 was baptized and emerged water cooled, leaving the legendary air cooled engine to live in Porsche history.

The total and complete redesign of the 911 engine was fitted with the vintage plastic "T" style air distributor that Porsche has used since the early 911 days. This intake system was found on virtually all 911 Carrera's until the arrival of the DFI cars in 2009.

The unique, innovative and patented design of the IPD Plenum employs a "Y" design that improves performance by channeling air left and right to the cylinder banks more efficiently. This design reduces air flow turbulence and increases air flow velocity resulting in substantial power gains throughout the entire rpm band.

The IPD plenum not only delivers impressive power and torque increases but also creates a more linear power and torque band. Tiptronic customers even claim considerable improvements with more positive shifting after installing the IPD Plenums.

Porsche introduced all 996 C2's with conventional cable throttles while all C4's were equipped with E-gas throttles. This was for the model year 98 in Europe and 99 in the US.

The IPD "Y" designed Cable plenum is a direct factory replacement of the OE "T" style air distributor. The IPD Plenum provides impressive max horsepower gains of 28 in the mid range and an additional 12 horsepower on top.

The IPD Plenum is the absolute single best modification that can be installed on these early under powered 996 Carreras and will transform your Porsche driving experience.

Installation is relatively easy and straight forward for mechanically inclined DIY customers although IPD strongly recommends having a qualified Porsche technician perform any IPD Plenum installation.

To confirm whether your Porsche is a Cable or E-gas throttle simply look at your throttle body for either a black electronic module (E-Gas) or a conventional spring / cable throttle control.

Porsche has been controlling engine output by restricting the inlet track for decades. This has been successfully accomplished by utilizing smaller throttle bodies. This simple power control solution has been a very effective way of preventing lower level models from out performing certain flagship models, especially models with prolific racing pedigree. Although the factory engine packages are fantastic performance machines, they are engineered and developed to achieve specific performance numbers that satisfy a target demographic and compete with rival brands. Unfortunately driving enthusiasts who seek an elevated Porsche driving experience require performance levels well outside the target market.

All of the IPD Plenums deliver substantial power and torque gains, but when combined with larger throttle bodies they perform even better. All of the IPD "Competition" Plenums utilize the next largest size throttle body offered by Porsche. In this case, the Competition Carrera upgrades the factory OE 74mm throttle body with Porsche's 82mm 997 GT3 throttle body. All of our Competition Plenums are designed to perform with cars equipped with high performance exhaust systems. The more extensive the exhaust system (headers, kats and mufflers) the better. Optimizing air intake and exhaust together creates a balanced performance package that allows the engine to inhale and exhale more air thus creating more power and torque.

IPD has pioneered another new Plenum design with the Competition Carrera Plenum. Laminar flows and volumetric efficiencies have been further enhanced with our unique and innovative internal merge collector area. This completely new approach has yielded not only great performance gains but more linear power delivery and improved throttle response as well. Gains vary depending on pre-existing mods and quality of after-market exhaust installed. As we all "should" know, horsepower and torque become harder to find and typically more expensive as we climb the proverbial performance ladder. That being said, performance components yield different power gains depending on the order they were installed. IPD tests and evaluates all products on bone stock cars, this establishes a level playing field and a better "apples to apples" comparison. The Competition Carrera Plenum however is designed to work with applications that are already moderately to heavily modified. Power gains will vary with each Carrera, but the bottom line is, there will be noticeable and impressive gains that are sure to make any Porsche Carrera driving enthusiast smile.

Power improvements will be fully realized once the factory ECU/DME makes all the necessary "adaptation" requirements. This process can be expedited with a series of "hard pulls" or spirited full throttle acceleration runs through the gears. Of course this should only be performed on a closed course circuit.
