Forge Motorsport High Flow Inlet Hose for BMW Mini F66

*All Clearance sales are final. Returns will not be accepted*

Unlock the full potential of your BMW MINI’s F66 B48 engine with FMINLH27, Forge Motorsports high-flow inlet pipe performance upgrade. Designed to eliminate the restrictive factory inlet, this upgrade significantly improves airflow to the turbocharger, allowing your engine to breathe more freely and respond faster under throttle. Constructed from high-quality 5 ply silicone and stainless-steel reinforced wire for durability and heat resistance, the high-flow inlet pipe features smooth inlet track. The result is improved turbo spool, sharper throttle response, and increased power especially noticeable on tuned or modified vehicles.

This inlet pipe is a direct bolt-on replacement for the OEM unit, requiring no permanent modifications and ensuring a precise, factory-quality fit. Whether you’re chasing maximum performance on track days or simply want a more engaging driving experience on the road, this upgrade delivers measurable gains and enhanced engine sound under load.

FMINLH27 can be used with the OE airbox or aftermarket induction kit’s like Forge Motorsports carbon solution FMINDK61, so it’s a product to suit all preferences.

During development testing, we found that using oversized aluminum piping led to significant heat soak. While initial power gains were impressive, repeated dyno testing revealed a drawback: by the third pull, the aluminum pipe had absorbed and conducted excessive heat, resulting in a noticeable reduction in performance.

By switching to a silicone hose design, this issue was eliminated. Silicone does not store or conduct heat as effectively as aluminum, preventing heat soak. Even after six consecutive dyno pulls, the silicone hose maintained a stable temperature and showed no reduction in power output.

The Forge Motorsport high-flow inlet hose improves your vehicle’s airflow in several key ways. First, we eliminate the internal muffler found in the OE pipework. While this component is designed to reduce intake noise and create a more refined engine note, it also introduces turbulence and restricts airflow. These restrictions become even more apparent on tuned vehicles and are often the first area our engineers target for improvement.

With the factory limitations removed, the next step is increasing the internal diameter of the Forge design. A larger bore allows a greater volume of air to flow directly into the turbocharger, enabling more air to be compressed thanks to the increased capacity. This results in improved throttle response, particularly when accelerating after long periods of deceleration or during gear changes, as more air is retained within the intake system.

Not only does FMINLH27 deliver enhanced performance, but it is also engineered for exceptional durability. As previously mentioned, it is manufactured from our high-performance silicone featuring a reinforced 5-ply construction combined with an advanced fluoro lining for superior reliability.

The inner fluoro lining offers outstanding resistance to oil, fuel vapors, coolants, and chemical degradation, effectively preventing permeation and significantly extending service life. Additionally, due to the increased length and internal volume, integrated metal strengthening rings are molded within the silicone to prevent collapse under load—an issue commonly found in inferior products.
