Do88 Intake Plenum for Porsche 992 Carrera & Turbo Models (2020 and Later)

Description

Elevate your 992-series Porsche 911’s throttle response and airflow with the DO88 Performance Plenum (TR-300-992). This upgraded inlet plenum swaps in for the factory unit with a smarter Y-shaped design, reducing backpressure and improving air distribution through the engine. Cast from high-grade aluminum and CNC-machined for precision, it flows ~5 % more air than stock (at 0.1 bar) according to DO88’s CFD and flow-bench testing. The kit includes durable silicone couplers and all mounting hardware — transforming intake feel with measurable performance benefits.

Fitment Notes

• Compatible with Porsche 911 (992.1 / 992.2) — Turbo / Turbo S, Carrera / Carrera 4 / Carrera S / GTS / GTS 4, etc. 

• Replaces OEM plenum part numbers: 0PB128335C, 0PB128335A, 0PB128333E. 

• Uses DO88-supplied silicone hoses — ensures tight fit and longevity. 

• Because this is a high-flow part, pairing with an upgraded intake or tune can maximize gains.

Included

• Y-shaped cast-aluminum performance plenum (TR-300-992)

• CNC-machined connector ports for secure, leak-free hose attachment

• Matching silicone couplers / hoses for 992-specific install

• Installation hardware and detailed instructions

Product Specs

• Increased airflow: 846 CFM measured at 0.1 bar (~1.45 psi), about 5% higher than OEM.

• Construction: Free-form cast aluminum for strong internal flow paths.

• Design: Y-shaped internal layout improves distribution and reduces pressure loss vs the stock T-shaped plenum. 

• Weight: ~2.5 kg as listed by DO88. 

• Durability: CNC-machined connections for robust and precise hose attachment.

Product Features

• Optimized Airflow Distribution — The Y-shaped design provides more balanced air flow to each side of the intake manifold, improving response and torque.

• Reduced Restriction — Improved internal geometry reduces backpressure and improves turbo efficiency at higher boost levels.

• High-Quality Build — Made from cast aluminum with CNC-machined ports, blending strength, precision, and weight savings.

• Easy to Install — Comes with custom silicone couplers and mounting hardware, making the upgrade relatively straightforward.

• Track & Street Versatility — Whether you’re tuned for track or building a high-performance street car, this plenum supports higher airflow demands.

• Proven Performance — Validated via CFD and Superflow flow-bench testing, giving both confidence and real-world gains.
