MAD introduces their G-chassis B58 BMW Turbo Inlet/Resonator Delete Pipe, a product designed to optimize airflow from the intake to the turbo, eliminating restrictions and increasing the inlet diameter for improved power and turbo efficiency.
The MAD G-chassis turbo inlet pipe offers a seamless replacement for the factory OEM unit.
The OEM turbo inlet in plastic construction is prone to pressure-related cracks and features a flow-hindering "resonator." Additionally, the factory piping has a smaller diameter that hinders performance. MAD's Aluminum G-chassis B58 Turbo Inlets provide a wider diameter and eliminate the factory resonator, resulting in smoother and more direct airflow to the turbo, along with an enhanced induction sound.
Key Features and Benefits
• Boosts turbo airflow
• Enhances engine responsiveness
• Durable aluminum construction surpasses the stock plastic inlet
• Removes the factory sound resonator for an improved auditory experience
• Maintains an understated OEM appearance
