MAD BMW F Chassis B58 Turbo Inlet Upgrade

The MAD F-Chassis B58 Turbo Inlet Upgrade (also known as a resonator delete pipe) optimises airflow from the intake to the turbo, removing restrictions and increasing inlet diameter for improved power and turbo efficiency. It's a seamless replacement for the factory OEM unit.

The OEM plastic turbo inlet is prone to pressure-related cracks and includes a flow-hindering resonator, while its smaller diameter limits performance. MAD's aluminum F-chassis B58 inlet offers a wider diameter and eliminates the factory resonator for smoother, more direct airflow to the turbo, plus an enhanced induction sound.

Key features & benefits

• Anodized black finish.
• Boosts turbo airflow and engine responsiveness.
• Durable aluminum construction that outlasts the stock plastic inlet.
• Removes the factory sound resonator for an improved induction note.
• Maintains an understated, OEM-style appearance.
• Pairs with the MAD intake & silicone inlet to remove both resonators completely.
