Dinan High Flow Intake System - 2001-2006 BMW 325i

If you're looking to boost your engine's breathing, Dinan's High Flow Intake System is here to help! This system features a specially designed injection molded replacement lid for your stock air box, crafted to increase overall volume and accommodate a high flow filter element. This means you're getting the best possible intake air-flow for your vehicle.

The lid is made from a unique composite material, selected for its impressive ability to resist the heat that can sap your engine's power. Plus, it comes with an O-ring that seals the air box tightly, ensuring maximum pressurization and insulation against heat-soaking. This setup optimizes performance, no matter how you're driving.

But that???s not all! The system also includes a secondary intake duct that channels in extra cool, oxygen-rich air through the factory brake cooling duct. This is a fantastic way to enhance performance as your speed picks up on the road.
