Unlock the full breathing potential of your E9X M3’s legendary S65 V8 with the Dinan High Flow Carbon Fiber Intake. Engineered with premium materials and precision design, this intake delivers a significant airflow improvement while adding a refined motorsport aesthetic under the hood. The system features a beautifully crafted carbon fiber connecting pipe paired with injection-molded rubber boots, all sealed from under-hood heat using Dinan’s custom-molded divider plate. This divider includes an integrated high-flow passage that mates seamlessly with the factory airbox to keep intake air cool and consistent—even under aggressive driving.
What sets this intake apart is its intelligent design and thermal efficiency. Carbon fiber and high-grade plastics were chosen not only for their structural benefits but also their insulating properties, allowing the components to resist heat soak and cool down more rapidly than metal intake systems. With a 30% increase in cross-sectional area and a large free-flowing cotton gauze filter, the Dinan intake ensures the S65 has the airflow it needs at high RPM—delivering measurable gains of up to 8 horsepower and 5 lb-ft of torque at 8200 rpm. The result is sharper throttle response, improved top-end breathing, and a deeper induction sound that enhances every drive.
