Dinan carbon fibre induction for BMW M5 F90 2018 to 2023

Unlock effortless breathing for the S63 bi‑turbo V8 with Dinan’s premium carbon fibre induction system. This fully sealed, high flow upgrade replaces the factory airboxes with beautifully engineered carbon plenums and a central feed that delivers cooler, denser air for sharper throttle response, stronger midrange and a stunning motorsport look across the entire bay.

If you are chasing a high quality BMW M5 F90 intake upgrade that blends real performance with show car finish, this is the one we rate most highly. We run it ourselves and our customers consistently report crisper response, smoother delivery and a purposeful induction note under load without unwanted drone.

Performance benefits

• Greater airflow capacity with reduced restriction, allowing the turbos to achieve target boost with less effort.
• Measured flow increase of 11 percent per bank at 28 inches H2O – from 575 CFM to 637 CFM.
• Enlarged carbon airboxes with approximately 31 percent more internal volume for a bigger reserve of cool air.
• High flow panel filters offering around 35 percent more surface area per side for efficient breathing.
• Lower pre‑turbine pressure drop can reduce turbo shaft speed and compressor outlet temperatures, supporting reliability and repeatable performance.
• Refined induction character – subtle at cruise, more assertive under throttle.
• UV‑coated 2x2 carbon weave for heat resistance and long lasting gloss that transforms the engine bay.

Engineered details that make the difference

• Dual sealed carbon plenums feed each bank of the S63 while isolating intake air from under‑bonnet heat.
• Functional central spine inlet draws additional ambient air from behind the kidney grilles and distributes it to both sides.
• Optimised duct geometry minimises pressure depression across the entire intake path.
• Direct replacement design retains OE mounting points and sensors for a clean, factory‑style fit.
• Works brilliantly on standard cars and scales with software, downpipes and optional Dinan turbo inlets.
