Why Choose the Forge F66 Induction Kit?
The Forge Motorsport FMINDK61 has been developed to address airflow restrictions within the original MINI intake system while preserving its factory cold air supply.
Unlike basic open-filter induction kits, this system uses an enclosed carbon fibre airbox to help protect the filter from surrounding engine-bay heat.
Key features and benefits:
- Premium prepreg 2×2 twill carbon fibre airbox.
- Enlarged 100mm intake connection compared with the original 88mm design.
- Approximately 46.7% greater cross-sectional area at the enlarged connection.
- High-flow synthetic nanofibre cone air filter.
- Improved airflow to the turbocharger.
- More noticeable turbo spool and induction sound.
- Retains the factory lower airbox and cold air feed.
- Vehicle-specific fitment for compatible MINI F65 and F66 applications.
- Up to 11 bhp and 17 Nm gains recorded when combined with the Forge FMINLH27 high-flow inlet hose.
- Direct-fit design with replacement inlet hose included.
The Forge F66 Induction Kit is an excellent choice for MINI owners who want to improve the driving experience without sacrificing the factory cold air intake arrangement.

Forge F66 Induction Kit Performance and Airflow Improvements
Larger 100mm Intake Connection
One of the most important improvements introduced by the Forge FMINDK61 is its enlarged intake connection.
The factory intake connection measures approximately 88mm, while the Forge replacement increases this diameter to 100mm.
This represents an approximate 46.7% increase in cross-sectional area at the enlarged connection, helping reduce potential intake restriction.
The larger connection is designed to improve the flow of incoming air through the intake tract, supporting the demands of the turbocharged MINI engine.
When combined with the specially developed high-flow air filter, the system provides a more performance-oriented intake arrangement.
Improved Throttle Response
The Forge F66 Induction Kit has been developed to support more efficient airflow to the turbocharger.
By reducing restrictions in the intake system, Forge aims to improve engine responsiveness and help the turbocharger operate more efficiently.
Drivers may notice:
- Sharper throttle response during acceleration.
- More pronounced turbocharger spool.
- Improved engine response through the mid-range.
- Greater induction sound under load.
- A more engaging driving experience.
The extent of these improvements will depend on the vehicle’s specification, condition and supporting modifications.
Carbon Fibre Airbox with Premium Motorsport Construction
Prepreg 2×2 Twill Carbon Fibre
The Forge FMINDK61 features a high-quality carbon fibre upper airbox designed specifically for the MINI F66 platform.
Manufactured using prepreg 2×2 twill carbon fibre, the enclosure is formed through an autoclave manufacturing process using precision tooling.
This construction offers excellent dimensional consistency and a premium appearance.
The carbon fibre housing is finished with a protective anti-UV gloss coating designed to maintain its finish during repeated engine heat cycles.
The result is an induction system that looks as impressive as it performs.
Enclosed Airbox for Better Heat Management
The Forge F66 Induction Kit uses an enclosed airbox rather than leaving the filter exposed to hot air circulating around the engine.
This enclosure helps separate the performance air filter from the surrounding engine bay, reducing exposure to unwanted heat.
Forge’s design also retains the factory lower airbox and original cold air feed.
These components continue to supply fresh outside air to the filter, helping maintain a consistent supply of cooler intake air.
This makes the FMINDK61 particularly appealing to enthusiasts looking for a properly engineered induction upgrade.

High-Flow Synthetic Nanofibre Air Filter
The Forge F66 Induction Kit replaces the standard panel-filter arrangement with a specially developed high-flow cone filter.
This performance filter features synthetic nanofibre filtration media with a pleated design to increase the available filtration surface area.
The larger effective surface area helps support airflow while maintaining the filter’s primary role of protecting the engine from airborne contaminants.
Filter advantages include:
- High-flow synthetic nanofibre filtration media.
- Pleated construction to increase surface area.
- Designed for the Forge carbon fibre enclosure.
- Supports increased intake airflow.
- Replacement filter availability through Forge Motorsport.
Unlike a generic universal air filter, this component has been selected for the FMINDK61 intake arrangement.
Forge F66 Induction Kit Dyno-Tested Performance Gains
Forge Motorsport has tested the FMINDK61 induction system to assess its performance improvements over the factory arrangement.
Independent testing was conducted at Performance Remap in Gloucester using a four-wheel-drive dynamometer.
Manufacturer-reported results:
| Performance Measurement | Recorded Improvement |
|---|---|
| Peak wheel horsepower | Up to +11 bhp |
| Peak torque | Up to +17 Nm |
| Power improvement | Reported from approximately 3,000 RPM |
| Test setup | FMINDK61 with FMINLH27 |
During testing, Forge reported improvements beginning at approximately 3,000 RPM, with power gains continuing towards the upper engine speed range.
Important: These performance gains were achieved using the Forge FMINDK61 induction kit together with the separate FMINLH27 high-flow inlet hose. The figures should not be interpreted as guaranteed gains from FMINDK61 alone.
Actual results can vary depending on vehicle condition, engine configuration and additional modifications.

Enhanced Turbocharger and Induction Sound
Performance isn’t the only reason to upgrade your MINI’s factory air intake.
The Forge F66 Induction Kit also delivers a more noticeable induction soundtrack, making everyday driving more engaging.
Compared with the original factory airbox, the Forge intake allows more of the turbocharger’s natural operating sounds to be heard.
Depending on driving conditions, drivers can experience:
- More pronounced turbo spool during acceleration.
- A deeper performance intake sound.
- More noticeable turbo-related sounds when lifting off the accelerator.
- A sportier overall driving character.
The enclosed carbon fibre housing creates a balance between improved induction sound and an engineered cold air supply.
For MINI enthusiasts who enjoy the sound of a turbocharged engine, this is one of the most attractive features of the FMINDK61.
Recommended Upgrade – Forge FMINLH27 High Flow Inlet Hose
For MINI Cooper S and JCW owners seeking additional induction performance, Forge Motorsport recommends pairing the FMINDK61 with the FMINLH27 High Flow Inlet Hose.
This separately available component is designed to improve airflow through the turbocharger inlet system.
Together, the components provide a more comprehensive intake upgrade than the induction kit alone.
The combination was also used during Forge Motorsport’s published dynamometer testing.
