MAD BMW F3x B58 M140 M240 340 440 High Flow Air Intake W/ Heat Shield
The MAD B58 High Flow Air Intake gives your B58 BMW more airflow, more power and a more aggressive sound. A mandrel-bent, powder-coated aluminum intake tube pairs with an advanced synthetic filter that's washable and reusable — a cost-effective, high-performance alternative to disposable elements.
It's a direct, fully reversible replacement for the factory intake that retains the stock cold-air ducting and bottom heat shielding, and installs in minutes with basic hand tools. A heat shield is included.
