The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.
This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies. Valeo is an OEM manufacturer for many BMW alternators - save money by buying the same alternator in a different box!
Are you running more E85 or making more power on pump gas than your HPFP (High-Pressure Fuel Pump) can support?
Fuel-it has developed a port injection kit for your S55 that will provide you with the additional fueling capacity that you need to be able to run up to 100% E85 on stock or upgraded turbos.
What is port injection?
Port injection is a kit that is installed between your intake manifold and the cylinder head that runs off the low-pressure supply to provide you with more fueling than your stock system is capable of. It's a relatively easy system to install and does not require any permanent modification to your car.
Port injection kits are offered in five different packages to meet your needs:
Base port injection kit: (included in Bronze, Silver or Platinum Kits)
Bronze kit includes:
Silver kit includes:
Platinum kit includes:
*These kits are available for off-road use only
*All port injection kits are built to order.
*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.
