Designed with precision engineering, our plenum improves the airflow dynamics for enhanced performance without compromising OEM compatibility.\u003c\/h2\u003e\n\u003ch2\u003eBy 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.\u003c\/h2\u003e\n\u003ch2\u003eTaking 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.\u003c\/h2\u003e\n\u003ch2\u003eTesting on our flow bench revealed an impressive 53% reduction in overall pressure drop at 600 CFM:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch2\u003eStock plenum: 35.0 inH20 @ 600 CFM\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch2\u003eCTS plenum: 16.5 inH20 @ 600 CFM\u003c\/h2\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eOur intake manifold comes pre-assembled and pressure tested, guaranteeing a hassle-free installation.
