CTS Turbo Billet Intake Manifold Plenum DAZA/DNWA - 2018+ Audi 8V/8Y RS3/Audi 8S TTRS 2.5T EVO

Introducing our latest innovation: Our Billet Intake Manifold Plenum crafted specifically for the Audi RS3/TTRS DAZA/DNWA. Designed with precision engineering, our plenum improves the airflow dynamics for enhanced performance without compromising OEM compatibility.

By strategically relocating the throttle body mounting flange outward, we eliminate the need for the OEM spacer, optimizing airflow directly to the nearest engine cylinder. Through meticulous design and rigorous CFD testing, we’ve greatly improved the airflow efficiency. Our plenum features an expanded divider passage, enhancing overall flow rate while maintaining the stock flow distribution between engine cylinders.

Taking into consideration the firing sequence of 1-2-4-5-3, we’ve fine-tuned the plenum to simulate real-world motor conditions, ensuring optimal air distribution. Additionally, we’ve integrated 2 1/8 NPT ports for added versatility.

Testing on our flow bench revealed an impressive 53% reduction in overall pressure drop at 600 CFM:

• Stock plenum: 35.0 inH20 @ 600 CFM
• CTS plenum: 16.5 inH20 @ 600 CFM

Our intake manifold comes pre-assembled and pressure tested, guaranteeing a hassle-free installation. To complement its performance, we’ve finished the billet plenum with a sleek black anodized coating for durability and a refined aesthetic.

On a Stage 3 modified RS3, our plenum delivered a remarkable 45 WHP gain and 60 WTG increase over the stock intake plenum—with no additional tuning.
