Dinan Carbon Fibre Turbo Inlet Pipes / Intake Tubes for BMW M5 F90 & M8 F91 F92 F93 2018-2023 (S63/S63TU) - High-Flow Induction Ducts, Compressor Inlet Upgrade, Carbon Fiber Air Intake Pipes

Give your BMW S63 the airflow it deserves with Dinan’s high-flow induction tubes for the M5 F90 and M8 F9x platform. Swap out the restrictive OE ducting and let the compressors breathe. This upgrade removes the tight factory choke point ahead of the turbos and replaces it with a far larger passage from filter to compressor, transforming throttle response, mid‑range punch and top‑end pull.

Crafted from UV‑coated 2x2 carbon fibre with precision‑machined alloy turbo couplers, the assembly locks to the OE turbochargers using the original style connection for a quick, drama‑free install. The unique shape maximises cross‑section all the way to the compressor mouth, delivering around 200 percent more internal volume per side compared to stock, which means the turbos do not have to work as hard to hit target boost.

Proven gains: on a standard car you can see up to +22 WHP and +18 lb ft at 6500 rpm, with typical improvements of +11 WHP and +13 WTQ from 2000 rpm to redline. Pair with the Dinan cold air intake for the strongest overall efficiency, or run with factory airboxes for a simple, effective upgrade.

Beyond the dyno, the freer‑flowing design helps the S63 operate more efficiently. Benefits include reduced pre‑turbine backpressure, lower turbo shaft speed for a given boost level, cooler compressor discharge temperatures and greater headroom for higher boost targets as you continue your build.

Why enthusiasts choose this upgrade

• Massively increased internal diameter from filter to compressor inlet for superior airflow
• Approx. 200 percent more internal volume per side than OE ducting 105 cu in vs 35 cu in
• Lightweight carbon fibre construction that looks as good as it performs
• OE‑style click‑lock alloy adapters for a secure, straightforward fit
• Works with stock airboxes and the Dinan cold air intake third‑party intake compatibility not guaranteed
• Fast, bolt‑on installation with no permanent modifications

Fitment

BMW M5 F90 and BMW M8 F9x family. Ideal for S63 and S63TU applications where a high‑flow induction upgrade is desired.

What we have seen in the workshop

We have run these on customer cars and our own builds and the difference is immediate. Sharper response, stronger mid‑range, a harder charge to the limiter and a purposeful induction note. Feedback from our clients has been consistently positive with many noting cooler intake temps on back‑to‑back runs and improved repeatability.
