No one buys an M3 because they like limits. This carefully engineered kit matches the Rotrex C38 supercharger with the perfect hardware, software and tuning to take the factory 240 HP straight up to 360 HP (with the potential for even more power with additional upgrades). Best of all, if your craving for more power is still insatiable, there is a higher upgrade Level 2 featuring more boost and a front mounted air to air intercooler. The Active Autowerke supercharger systrem is truly modular and fully upgradeable. Running on 91-93 octane pump fuel with full emissions system intact, this system has stood the test of real world conditions and delivers thrill-worthy performance on demand while still retaining that BMW feel for a comfortable daily commute.

This is a complete plug and play solution to replace your stock Low-Pressure Fuel Pump (LPFP) with a new E85 certified bucketless assembly.

This solution provides up to 25% more flow than our standard Stage 2 LPFP upgrade and up to 150% more flow than the stock pump.

This pump will support up to 550whp running 85% ethanol and 600whp running 50% ethanol.

The Stage 2 bucketless kit includes the following:

- A custom anodized billet fitting for the pump output and stock fuel line connection.
- Our custom billet aluminum anodized bracket for the pump and float assembly
- Two cotter pins to secure your float assembly
- A new E85 compatible Walbro 450 pump
- Spare vent tube clip
- A new Walbro filter

If you still need more flow, the Stage 3 upgrade is also available and can be added to your Stage 2 bucketless pump.

The Stage 3 upgrade kit includes:

- A complete plug and play solution by simply adding the secondary module
- Our custom billet aluminum fitting to run both pumps in parallel
- A new E85 compatible Walbro 450 pump
- Wiring harness for the secondary pump
- Spare vent tube clip
- A new Walbro filter

Recommended accessories:
- Lock Ring Removal Tool
- Hobb's switch
NOTE: These kits include a basic filter assembly. When using this filter, running the vehicle under low fuel conditions can cause fuel starvation issues. If you do hard straight line accelerations when you have less than 1/8 tank of fuel, we would recommend running our standard Stage 2, 3, or Stage 4 pump. In addition, if you intend to use this for road course applications, you may see starvation issues when running less than a half tank and doing long high G right turns. Again for those applications we'd recommend one of our standard pump applications.

This is a complete Low Pressure Fuel Pump (LPFP) upgrade that replaces your weak stock LPFP assembly with a high-flow E85-certified one. Standard Kit Includes: A brand new OEM LPFP bucket that is upgraded with a new Walbro 450 or 525 pump and filter. A new E85 compatible Walbro 450 pump (F90000274) that flows 50% more fuel than stock Optional A new E85 compatible Walbro 525 pump (F90000285) that flows 65% more fuel than stock NOTE: Owners with I-Drive may get a Fuel pump warning on the screen that says "Continued driving is possible. Have the system checked by your BMW center as soon as possible." As long as the car is running fine and does not exhibit any other symptoms, there is not an issue with the pump and this can be ignored. If you have any questions about this please feel free to contact us. Upgraded pumps pull more current, so if your EKP (LPFP control module) is weak, it may overheat causing it to shut down and need to be replaced. If this is a concern for you check out our Stage 3 fuel pump upgrade kits that retain the stock LPFP and add a secondary pump.

This is a complete plug and play kit to install a Bluetooth ethanol sensor in your E-Series BMW. (Check compatibility for your platform below) This kit replaces the stock fuel lines from the fuel tank to the engine bay with an upgrade -6an E85 compatible fuel line and adds an ethanol sensor and Bluetooth analyzer to monitor your ethanol content. This kit features a 0-5 volt analog output that integrates with the JB4, analog gauge, or any other ECU or tuner that supports 0-5 volt input. All of these kits utilize a custom billet aluminum fittings to integrate with the stock fittings so no modifications are needed. For your fuel line upgrade, choose the option that supports your current configuration. HPFP to the fuel tank: (Stock) This upgrade replaces both stock fuel lines with one upgraded continuous fuel line from the fuel tank to the HPFP and adds the ethanol sensor. Port Injection to the fuel tank: If you are running our port injection kit, this upgrade replaces the stock fuel lines from the tank to the engine bay, integrates the ethanol sensor and then utilizes a Y adapter to supply the HPFP and PI with fuel. Our custom fittings remove those tee's and extra fittings for a cleaner high flow setup. Non-Fuel-It! port injection to fuel tank: Choose this option if you are running a port injection kit that we did not manufacture or sell. This kit includes a longer 18" feedline from the Y to the port injection rail. You then cut the feed line to the length you need and install the included -6an female fitting or -6an female elbow to make the connection to your port injection rail. *These kits are available for off-road use only *Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated. *For the BMW N54 E-series JB4 platform connect the white wire to position #15 on the JB4 25 pin harness. Select WMI Ethanol Setup option 1 to enable pin location 15/16 flex fuel input. *For the BMW N55 E-series JB4 platform connect the white wire to position #16 on the JB4 25 pin harness. Select WMI Ethanol Setup option 1 to enable pin location 15/16 flex fuel input. *Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated.
