IPD Competition Plenum Intake for Porsche 981 GT4 and Spyder (2015–2016)

Description

The Porsche 981 GT4 / Boxster Spyder IPD Intake Plenum is a performance-focused airflow upgrade that eliminates the restrictive factory intake plenum in favor of a precision-designed, high-flow “Y”-shaped manifold. This optimized plenum promotes smoother, laminar airflow into the engine’s intake tract, which improves throttle response and enhances mid-range and high-RPM performance characteristics. Drivers will also notice a subtle increase in intake sound that enriches the engine’s auditory experience. This upgrade becomes increasingly beneficial when paired with other bolt-on modifications such as performance headers, ECU tuning, or a larger throttle body, helping the 3.8 L flat-six breathe more efficiently at elevated demands.

Fitment Notes

• Designed for Porsche 981 GT4 (2015–2016) and Boxster Spyder (2015–2016). 

• Direct bolt-on replacement for the stock intake plenum.

• Works with factory throttle body and intake hardware; larger throttle body upgrades may require a dealer adaptation procedure.

• Ideal when combined with other performance upgrades like headers or ECU tuning for maximum benefit. 

Included

• High-flow IPD intake plenum manifold designed specifically for the 981 GT4/Spyder. 

• Mounting hardware for direct installation. 

Product Specs

• Material: Precision-cast aluminum for strength and optimized airflow heat control. 

• Design: “Y”-shaped with dimpled interior surface to reduce turbulence and increase air velocity.

• Fitment: Direct replacement of factory intake plenum on 981 GT4 and Boxster Spyder models.

• Throttle Body Compatibility: Works with factory setup; GT3 throttle body adaptation may require dealer procedure for correct operation. 

Product Features

• Improves intake efficiency by reducing turbulence and promoting smoother airflow into the engine. 

• Enhanced throttle response and improved drivability due to increased air velocity. 

• Slightly richer intake sound enhances the driving experience without harsh resonance. 

• Direct bolt-on installation preserves OEM fit orientation and simplifies upgrade. 

• Great complement to performance updates such as headers, ECU tuning, or throttle body upgrades.
