Unlock more power, sharper response, and premium engine bay styling with the Dinan Carbon Fiber Cold Air Intake for BMW B58-powered F2X and F3X models.

Developed as the next evolution of Dinan’s acclaimed 6-cylinder intake systems, this fully engineered cold air intake improves upon the factory design with greater airflow capacity, reduced restriction, and enhanced turbo efficiency. The result is measurable performance gains of up to +15 HP and +13 lb-ft of torque at 6000 RPM on a completely stock vehicle.

This intake features a 30% larger sealed airbox that helps isolate intake air from engine bay heat while delivering greater airflow potential.

A custom high-flow filter offers 34% more filter surface area than OEM, while the optimised carbon fiber intake tube removes the factory baffling and Helmholtz chamber that disrupt airflow and mute induction sound. Dinan also includes a freer-flowing 8% larger air mass meter housing for maximum efficiency.

The result is stronger top-end power, improved throttle response, reduced turbo strain, and a far more engaging induction soundtrack.

Constructed entirely from premium carbon fiber with upgraded coatings for long-term durability, the Dinan intake dramatically enhances under-bonnet appearance while delivering proven performance.
