CTS Turbo Audi RS3/TTRS Billet Intake Manifold Plenum DAZA/DNWA

Experience unmatched performance with the CTS Turbo Billet Intake Manifold Plenum, engineered specifically for Audi RS3 and TTRS models equipped with the DAZA or DNWA 2.5T engines. This high-performance plenum is designed to enhance airflow efficiency, eliminate the OEM spacer, and maintain full compatibility with factory components. By relocating the throttle body flange outward and expanding the internal divider passage, airflow is optimized for all cylinders—especially the one closest to the inlet—ensuring smoother, more balanced delivery and a measurable increase in power.

Precision CNC-machined from 6061 billet aluminum and finished in a durable black anodized coating, this intake manifold plenum is as functional as it is visually refined. Real-world CFD analysis and bench testing show a 53% reduction in pressure drop at 600 CFM compared to the OEM unit, significantly improving throttle response and horsepower. On a Stage 3 RS3, this upgrade delivered gains of 45 WHP and 60 WTQ without any additional tuning. Designed to simulate real engine dynamics, including the 1-2-4-5-3 firing order, this plenum ensures optimal air distribution under high-performance conditions. It comes pre-assembled and pressure tested for easy installation and includes two 1/8" NPT ports for additional versatility. Compatible with both CTS and OEM throttle body inlets, this is the ultimate upgrade for RS3 and TTRS owners seeking serious performance gains.
