{"product_id":"cts-turbo-audi-rs3-ttrs-billet-intake-manifold-plenum-daza-dnwa","title":"CTS Turbo Audi RS3\/TTRS Billet Intake Manifold Plenum DAZA\/DNWA","description":"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.\n\nBy 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.\n\nTaking 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 2x 1\/8 NPT ports for added versatility.\n\nTesting on our flow bench revealed an impressive 53% reduction in overall pressure drop at 600 CFM:\n\u003cul\u003e\n \t\u003cli\u003eStock plenum: 35.0 inH20 @ 600 CFM\u003c\/li\u003e\n \t\u003cli\u003eCTS plenum: 16.5 inH20 @ 600 CFM\u003c\/li\u003e\n\u003c\/ul\u003e\nOur intake manifold comes pre-assembled and pressure tested, guaranteeing a hassle-free installation.

The testing was conducted at Racing Greed, where the primary roller—responsible for measuring power—is positioned under the rear tires. This configuration isn’t ideal for my car, as the majority of its power and torque are delivered through the front wheels.\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cem\u003eOnce output exceeded 1000whp, the Haldex system was no longer able to effectively transfer any more additional power to the rear, resulting in the irregularities seen in the graph. Because the dyno measures primarily through the rear roller, it couldn’t accurately capture the car’s true performance under these conditions. Rotating the car on the dyno would have produced a cleaner looking graph.\u003c\/em\u003e\n\n\u003cem\u003eWe confirmed this by dyno testing the car at Evolution Auto in Richmond, where the dyno’s primary roller is positioned at the front. There, the results were exceptionally smooth, supporting the conclusion that the earlier inconsistencies were due to dyno configuration rather than the car itself.\u003c\/em\u003e\n\n ","brand":"CTS TURBO","offers":[{"title":"Default Title","offer_id":41814182953021,"sku":"CTS-HW-524","price":1699.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0898\/5024\/files\/CTS-HW-524-4.jpg?v=1731526907","url":"https:\/\/www.euromotiv.com\/fr\/products\/cts-turbo-audi-rs3-ttrs-billet-intake-manifold-plenum-daza-dnwa","provider":"Euromotiv","version":"1.0","type":"link"}
