BMW M240i Performance Air Intake - Dinan - Closed Cold Air Intake - Carbon Fiber - 2019-2021. This sealed carbon fiber system increases airflow and efficiency while keeping intake temps under control.

Engineered for the B58 M240i, Dinan expands the airbox and filter to cut restriction, sharpen throttle response, and reduce turbo effort. The carbon fiber intake tube eliminates factory baffling and the small Helmholtz chamber that disrupt flow, creating a smoother path and allowing the natural induction note with minimal added volume. A fully closed design pulls cold outside air for consistent performance, while premium carbon construction is built to last.

Features

• Gains of up to +15 hp and +13 lb-ft at 6000 rpm on a stock vehicle
• 34% larger filter area (102.1 sq in vs. 76.3 sq in) for improved flow

• 50-state emissions legal for 2019-2021 M240i (CARB EO D-176-56)
