DINAN Cold Air Intake - BMW 335i/435i/M2/M235i (12-18)

Unlock more power, response, and sound from your N55-powered BMW with the Dinan Carbon Fibre Cold Air Intake. Designed to enhance efficiency while maintaining the factory-sealed configuration, this system maximizes cold-air delivery through an optimized carbon fibre intake tube and enlarged airbox — delivering performance gains without compromise.

The precision-engineered carbon fibre tube mirrors the OEM layout but reduces restriction thanks to its straighter, freer-flowing design. Air is fed into a larger-volume sealed airbox housing an oversized cylindrical filter, producing both measurable power gains and a deeper, sportier induction tone.

Expect up to +10 HP and +15 lb-ft of torque (on most N55 platforms) with improved throttle response and reduced heat soak, all while preserving factory drivability and emissions compliance. Installation takes under an hour for an instant transformation in both sound and performance.

Features & Benefits:

• +10 HP / +15 lb-ft gains (most platforms)

• +8 HP / +6 lb-ft gains (BMW M2 N55)

• Optimized carbon fibre intake tube for improved airflow
