IPD Porsche 996 GT3 Mark II 3.6L Competition 82mm Plenum (‘04)

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).

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 74mm “Competition” Plenum is designed to function with more seriously modified Turbos developing over 600+ horsepower. Although this 74mm application has been used with great success on a variety of Turbos ranging from mildly modified to 1000+ HP.

This application requires the larger 74mm Porsche throttle body (additional purchase required) and comes with additional hardware to complete the kit. This “Competition Turbo” Plenum will help modified 996 Turbos realize maximum performance.

The increased air flow and air speed develop by the larger Plenum is designed to work with larger turbos, intercoolers, intake piping, high flow Y-Pipes and more aggressive software.

Horsepower gains start around 35 hp and deliver max power slightly higher in the rev range creating better top end performance without the drop in power experienced with the factory air distributor.
