The MAXBoost doesn’t just add power, it transforms the entire character of the engine, giving your FIAT 124 the strength to match its newfound responsiveness.

MAXFlow Intake System 

A completely sealed performance intake system designed specifically for the FIAT 124 Spider (fits both ABARTH and non ABARTH models). Developed in partnership between MADNESS Autoworks and BMC Air Filters Italy. This is the same filtration technology used on many high power exotic cars worldwide.

This is a true bolt in system built around the premium BMC OTA (Oval Trumpet Airbox) filtering system. No inflated dyno claims, just a solid, properly engineered intake that delivers excellent filtration with minimal restriction and a great induction sound.

What’s Included in the Kit
- BMC Carbon Canister with the OTA Filtering System  
- High performance silicone connectors  
- Aluminum tubing powder coated Gloss Red for a durable, long-lasting finish  
- TIG welded tubing for show quality appearance  
- Crankcase vent filter  
- BMC canister filter manufactured in Italy  
- All necessary mounting hardware  

Key Design Advantages
- Fully sealed system that channels cold air directly to the filter  
- Even piping diameter throughout to reduce turbulence  
- Solid mounting design that eliminates rubbing on the hood or interference with airbag sensors (common issues with other intakes)  
- BMC OTA system uses a patented internal airflow deflector and “Trumpet” design that works in a pressure regime rather than depression, delivering a constant high volume of air with very low pressure drop  
- 5-layer carbon fiber airbox for excellent thermal insulation from engine heat  
- Multi layer pre oiled washable/ regenerable filter element that never needs to be replaced, only cleaned and re oiled with the optional BMC Cleaning Kit  

Why It Matters for Stage 2
The MAXFlow Intake feeds the MAXBoost ECM and GOPedal Plus a higher volume of cooler, cleaner air. This supports the power gains, improves throttle response feel even further, and adds a satisfying induction sound under acceleration which completes the Stage 2 transformation.



The Complete Stage 2 Package
The GOPedal Plus gives you instant, customizable throttle response.  
The MAXBoost ECM delivers the real horsepower and torque to back it up.  
The MAXFlow Intake (select color at checkout) supplies the freer flowing, cooler air that lets both modules work at their best.

All electronic controls are managed from one single app, creating a seamless, integrated experience that no other company currently offers for the FIAT 124.

This is Stage 2 done right... safe, reversible, fully adjustable, and designed by enthusiasts who drive these cars every day.
