The TPE Precision F56 MINI Airbox Kit is a fully enclosed high-performance cold air intake system engineered specifically for the F56 MINI platform. Designed to maximise airflow, reduce heat soak, and dramatically enhance turbo acoustics, this intake delivers proven performance gains without compromising efficiency or OEM-style drivability.

Developed for enthusiasts who demand more from their MINI, the system combines increased intake volume, dual-source cold air delivery, and aggressive induction sound in a true plug-and-play package.

Features: 

• Massive 90mm high-flow performance air filter
• True plug-and-play installation
• Enlarged high-capacity airbox lid
• Integrated secondary air diverter system
• MAF adapters included for LCI and Pre-LCI MINI models
• Fully enclosed cold air intake design
• Increased turbo induction and blow-off valve sound
• Heat-resistant advanced polymer construction
• Optional strut bar compatible version available

Performance Gains

The TPE Precision Airbox Kit has been independently tested under identical same day conditions, delivering measurable gains at the wheels without requiring an ECU retune.

• +16 WHP
• +20Nm torque

These gains were achieved with the airbox kit being the only modification changed during testing

The dyno test results were achieve on an F56 with the following modifications, note the MIN already had the Stage 1 tune, the results are not as a result of the ECU tune! 

• TPE Precision Turbo Inlet
• TPE Precision Intake Muffler Delete
• TRS Performance Stage 1 ECU Tune

Automatic gearbox torque limits remained active during testing.

Design & development 

Rather than redesigning components that MINI already engineered effectively, TPE Precision focused on solving the real airflow limitations of the F56 platform.

The OEM front air diverter already performs efficiently, offering minimal measurable gains when replaced. Instead, the focus was placed on increasing total intake system volume and airflow capacity.

The TPE Precision system incorporates a secondary cold air feed positioned within the cowl high-pressure zone. This supplies an additional source of dense, cold air directly into the enlarged airbox.

The result is:

• Increased mass airflow potential
• Greater internal intake volume
• Reduced airflow restriction
• Improved turbocharger efficiency
• Reduced heat soak under load

Unlike open cone intake systems, the TPE Precision Airbox Kit remains fully sealed, preventing hot engine bay air from contaminating intake temperatures.

Key Advantages

• Greater airflow volume than traditional enclosed intake systems
• More aggressive turbo acoustics than many open cone kits
• Consistent cold air delivery
• OEM-style fitment and reliability

This creates a genuine no compromise intake solution for the F56 MINI platform.

Materials and manufacturing

TPE Precision intentionally manufactures the intake system using advanced polymers rather than metal construction.

Unlike metal heat shields, polymers do not absorb and retain heat like a thermal battery. This helps maintain lower intake temperatures during repeated pulls and spirited driving conditions.

The filter receives a continuous supply of cold air from:

1. The OEM front air diverter
2. The secondary cowl-mounted air feed

This approach delivers:

• Lower intake temperatures
• Improved thermal consistency
• Reduced heat soak
• More consistent performance under load

The kit not only delivers performance but sound too

The secondary air feed system not only improves airflow but also fundamentally changes how turbo acoustics are transmitted into the cabin.

By routing the intake path towards the cowl area outside the insulated engine bay, turbocharger sounds travel through a shorter and less restricted acoustic path.

Sound benefits

• Louder turbo spool noise
• Sharper diverter valve acoustics
• Reduced sound damping
• Audible induction sound at light throttle
• Increased cabin feedback even with closed windows

The result is a raw, mechanical turbo sound profile that many traditional open cone systems struggle to replicate.

What does it fit

Compatible with:

• F56, F55, F57 MINI One
• F56, F55, F57 MINI Cooper
• F56, F55, F57 MINI Cooper S
• F56, F55, F57 MINI John Cooper Works (JCW)

Supports both:

• LCI MINI models models produced 2018 - 2022
• Pre-LCI MINI models models produced pre 2018

Options: 

The TPE Precision F56 MINI Airbox Kit is available in two fitment configurations:

• Standard version (non-strut brace vehicles)
• Ultra Racing strut brace compatible version

The Ultra Racing compatible version has been specifically engineered to provide clearance for vehicles fitted with the popular Ultra Racing front strut brace while maintaining full functionality and OEM-style fitment.

Importantly, the Strut Brace version will also fit vehicles not currently equipped with a strut brace. This allows owners to future proof their setup and retain the option of adding an Ultra Racing strut brace at a later date without needing to replace or modify the intake system.
