Show original supplier description

The JH Motorsports Stage 1 Supercharger Kit is engineered to significantly enhance the performance of your B6 or B7 Audi S4. This kit offers a substantial power increase, estimated at 80-100 wheel horsepower over the stock configuration, transforming the driving experience and providing a more visceral connection to the road. The kit is specifically designed for the 4.2L V8 40v engine found in the Audi S4. Installation of this supercharger kit requires a specific ECU calibration, which can be flashed at home using a JHM Tuning-Flashing Cable and software. For those who already possess a JHM POWER CONNECT Cable, the process involves accessing JHM's server with provided login credentials. Note that generic USB Vag Com cables are not compatible with the proprietary JHM software. It is crucial to understand that this product is strictly for off-road and racing competition use only. It is not legal for use on highway or street vehicles, and its installation may violate Federal or State emissions standards. Purchasers must acknowledge and agree that their vehicle will be used solely for racing applications and will not be operated on public streets or highways. JH Motorsports Inc. disclaims all liability for civil or criminal penalties arising from the use of this product on public roads. Additionally, this product may contain chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
