The E36 Intake Duct is engineered to optimize airflow to the intake system by replacing the left fog light with a CSL-style intake duct. This upgrade enhances engine breathing efficiency, contributing to improved performance and responsiveness. Manufactured from high-quality ABS material, the ducts feature a smooth, durable finish that resists discoloration from prolonged sun exposure. Designed for versatility, they can be installed as-is or painted to match the vehicle’s aesthetic. Compatibility extends to all E36 bumpers equipped with fog light openings, ensuring straightforward integration. Optional accessories include: Debris Mesh: Prevents large debris such as rocks and leaves from entering the intake, safeguarding engine components. 120mm Hose Attachment: Enables connection of a 120mm hose to the duct for customized airflow routing. 120mm Hose with Hose Clamps: Complete kit for secure hose installation. This product offers a plug-and-play installation experience, including all necessary mounting hardware. Note that fitting the 120mm hose adapter may require removal of one horn and headlight height adjuster, depending on the vehicle configuration. Important: This intake duct is not compatible with the OEM BMW Brake Cooling Funnel.
