Dinan Carbon Fibre/Fiber Cold Air Intake, Induction Kit & Performance Airbox for BMW X5M F85 & X6M F86 (2015-2017) | S63TU Twin-Turbo V8 High-Flow Carbon Intake Upgrade UK

Dinan carbon fibre induction upgrade for BMW F85 X5M and F86 X6M 2015 to 2017

Looking to free up your S63TU and sharpen response on your M SUV without compromising factory refinement? This Dinan carbon fibre induction system replaces the stock airbox with a high volume carbon assembly and custom high-flow filters, delivering increased airflow, a crisper throttle feel and a tasteful induction soundtrack. It also transforms the engine bay with a premium motorsport carbon weave that looks as good as it performs.

Proven airflow and volume improvements

• Filter surface area expands from approximately 89 in² stock to 292.4 in² with Dinan, an increase of about 228 percent for dramatically reduced restriction.
• Airbox volume enlarged by roughly 15 percent for better breathing and stronger performance across the rev range.
• Optimised design draws air across the entire filter surface rather than only front and rear faces, maximising usable area.
• Refined, sporty induction note under load while maintaining everyday comfort.

Why enthusiasts choose this carbon intake

• Beautiful carbon fibre lid and housing that elevate under-bonnet presentation on the F85 and F86.
• High-flow, platform-specific filters tailored for the S63TU twin-turbo V8.
• Engineered by Dinan for reliability, fitment and real-world performance.
• Pairs brilliantly with software upgrades. Consistent gains reported when combined with the DINANTRONICS Stage 2 Performance Tuner versus Stage 1.

Our experience

We have installed this Dinan carbon intake on customer X5M and X6M builds and feedback has been excellent.

It is the intake upgrade we recommend for S63TU drivers seeking an OEM-plus feel with measurable airflow benefits.
