Product Description
This NACA Duct with 3" openings is formed from high-impact 1/8" ABS. The inlet opening is 8.5x4.0" with a 1" flange all the way around that can be trimmed to fit as needed. It's designed as a universal duct with an extra large flange can accommodate a wide variety of mounting methods. The depth of the duct is 6.25".Due to the manufacturing process of how these ducts are formed, the dimensions are approximate. This duct is not specifically designed for any single BMW model. Optimal fitment is normally achieved through trimming or with additional pieces. This is a universal product intended for racing, where final installation is tailored to the car and use of the duct. We use this 3" hose all the time on our own BimmerWorld race cars, and it's something we highly suggest for general use and to keep spares of in your race trailer.
Highly recommended for E30s and all race cars. Sold individually for either left or right sides. Hose clamps sold separately.
