Description

The VF Engineering Supercharger Kit, part number VFK22-01, is a performance upgrade designed to significantly enhance the power and throttle response of BMW E46 3 Series models. This kit utilizes a centrifugal Vortech V3 Si-Trim supercharger and is meticulously engineered to preserve the original BMW quality, smoothness, and reliability. The system is configured to operate at 6 psi of boost, providing over 40% more power in most applications. The kit includes a hard anodized 6061-T6 aluminum bracket, a chrome moly support bracket, polypropylene air charge pipes, a K&N induction filter, high-capacity fuel injectors, and a crankcase ventilation system. It also incorporates a Bosch bypass valve circuit and uses an OEM serpentine belt, with the original active-spring belt tensioner remaining fully functional to eliminate belt slip. The air ducts are custom-molded for an OEM appearance and fit, and a removable plastic air box with a K&N induction filter is included for use in wet climates. Installation of this supercharger system is estimated to take approximately 8 hours and is designed to be fully reversible, meaning the original components can be reinstalled without issue. The VF Engineering software is crucial for smooth off-throttle cruising and deceleration, ensuring clean emissions and reliable ECU fuel management through extensive testing and re-writing of the Bosch and Siemens ECUs. This kit is fully OBD2 compliant. **Important Note:** This product is not compliant with the California Air Resource Board (CARB) and is not intended for use on public roads in California. This applies to any aftermarket product that does not display a CARB EO#. This supercharger kit is compatible with BMW 3 Series E46 models from 1999-2006, specifically the 323Ci, 323i (M52 2.5L), 325Ci, 325i, 325xi (M54 2.5L), 328Ci, 328i (M52 2.8L), 330Ci, 330i, and 330xi (M54 3.0L) with MS42, MS43, or MS45 ECUs.
