Take your smart fortwo 451 to the next level with the MADNESS Power Pack Stage 2!
Looking for more response, improved shifting and better airflow from your smart? The MADNESS Power Pack Stage 2 combines four of our most popular performance upgrades into one complete package designed specifically for the 2007–2015 smart fortwo 451.
Stage 2 builds on our popular Stage 1 Power Pack by adding upgrades to the intake system. The result is a more complete performance package designed to improve throttle response, transmission performance and engine airflow.
MADNESS AutoFlash TCM Module
The MADNESS AutoFlash TCM Module is designed to improve the operation of the smart's transmission by updating the TCU mapping. The revised programming helps improve shift times and addresses the factory torque limiter, helping the drivetrain respond more quickly when you ask for power.
MADNESS GOPedal Throttle Response Controller
One of our most popular smart upgrades! The MADNESS GOPedal connects directly to the factory accelerator pedal assembly and is designed to reduce the delayed throttle response commonly experienced with the smart fortwo 451. Multiple settings allow you to adjust throttle response to suit different driving styles.
BMC Performance Air Filter
Stage 2 adds a genuine BMC Performance Air Filter specifically designed as a direct replacement for the factory filter in the smart fortwo 451. BMC's performance filter provides increased airflow while maintaining excellent filtration, helping the engine breathe more freely without requiring modification to the factory airbox. The filter fits 2007–2015 451 models.
MADNESS Silicone Air Intake Upgrade Hose – Red
The factory intake incorporates a restrictive baffle that can interfere with smooth airflow. Our upgraded silicone intake hose replaces this factory section with an optimized design featuring smoother curves to improve airflow into the engine. The hose is manufactured from durable, long-lasting silicone and is designed specifically for the 2007–2015 smart fortwo 451 Non-Turbo.
Rather than addressing only throttle and transmission response, Stage 2 upgrades the complete driving experience. The AutoFlash and GOPedal improve how quickly the vehicle responds to driver input, while the BMC Performance Air Filter and MADNESS Silicone Intake Hose work together to reduce intake restriction and improve airflow.
You get better throttle response, improved transmission behavior and increased airflow in one carefully selected package while saving compared with purchasing the components individually.
Power. Response. Airflow. Savings.
