Burkhart Engineering E46 M3 CSL Airbox Snorkel Round Hose Adapter - Angled

This connector adapts OE-style CSL intake snorkels with triangular inlet into a round hose connection (83mm diameter). The adapter is designed with an angle for easier hose routing towards the driverside front bumper air inlet (both CSL and standard M3 bumpers).

Product Details

• Manufactured from 3D-printed PA-CF (carbon fiber reinforced nylon), offering strong mechanical and thermal stability for long-term use.
• Designed to fit both OEM and Karbonius CSL airbox snorkels without additional modifications.
• Angled adapter with round outlet (83mm) to bolt up to standard round hoses used on many intake or ducting setups.
• Helps maintain or improve airflow efficiency by connecting OEM-style snorkels to more universal ducting options.

Why Use This Adapter

• Enables compatibility between the existing CSL snorkel and aftermarket ducting that use round hose ends.
• Useful for custom air intake setups where factory routing doesn’t match aftermarket hose configurations.
• Helps prevent intake of hot engine bay air by allowing placement of ducting from cooler outside sources, depending on the setup.
