Dinan Carbon Fibre Induction Kit for BMW M3/M4 F80 F82 F83 (F8x) S55 Twin‑Turbo – Sealed Dual Airbox Performance Air Intake System Upgrade – Carbon Airbox CAI

Premium carbon induction system for BMW F8x M3 and M4 - S55 twin turbo

Looking to let your F80 M3 or F82 F83 M4 breathe properly and sound the part too? This carbon fibre intake from Dinan is a closed-box, twin-intake upgrade that feeds the S55 with cooler, high volume airflow and reduced restriction. Expect sharper throttle response, stronger mid-range and top-end pull, a deeper turbo soundtrack and a showpiece carbon weave under the bonnet.

The design uses a sculpted carbon tube that transitions smoothly into two enlarged air boxes housing oversized cylindrical filters. The closed configuration helps control intake air temperatures for consistent performance on the road and at the circuit, while the straighter tract and higher flow area minimise pressure drop. We run this on our own builds and have fitted it for many customers who rate the fit, finish and real-world gains in drivability and sound.

Why enthusiasts choose this carbon intake

• Closed air boxes feed cooler charge air for repeatable performance
• High-flow carbon ducting and larger filters reduce restriction
• Improved throttle response and torque throughout the rev range
• Richer, more purposeful induction tone with addictive turbo spool
• Immaculate carbon fibre that elevates any F8x engine bay
• Engineered specifically around the S55 twin-turbo straight-six
• Perfect partner for tuned or stock vehicles seeking efficient airflow

• BMW M4 F82 coupe - S55
