Up to 70 more horsepower for the Audi S4 (B9) with ABT power upgrade

By -

The separate ABT Engine Control (AEC) unit provides the driver of a current Audi S4 Sedan (B9) with an extra dose of speed, increasing the standard 354 HP / 369 lb-ft up to approximately 425 horsepower and 405 lb-ft of torque. The ABT Engine Control unit is installed additionally to the cars original ECU using a specifically developed wiring harness and mounting bracket for the engine bay, providing a safe and reliable performance upgrade.

To visually highlight the increased power ABT is offering various aerodynamic options like a front lip, front grille frame and fender inserts for the B9 S4 owner. A new muffler system with black chrome exhaust bezels helps to increase the sound performance and is available for the factory Audi rear skirt or in combination with an ABT rear skirt. An optional pre-muffler replacement pipe is also available to support the sound of the S4 even more.

The driving experience can be enhanced further with height adjustable suspension springs (lowering between 0.6 and 1.5 inches), anti-roll bars and a new set of wheels. ABT wheels of the DR, ER-C, FR or GR design are available in 19 or 20 inches with different finishing options. The German-based company is also customizing the interior of the Audi S4 by adding a carbon fiber shift knob cover, an ABT start-stop button and ABT integrated entrance lights.

All our ABT parts come with a warranty of 4 years or 100,000 miles. Installing parts like aerodynamics or wheels will not void the factory warranty of the car.
