Nostrum High Performance BMW S55 Twin Standard Bore Plus High Pressure Fuel Pump Kit

Want even more power out of your M3? The BMW S55 factory dual pump setup is already quite capable, however, there is always room for improvement.  This is where the Nostrum S55 HPFP kit comes in. Flowing 36% more fuel than stock, the Nostrum HPFP’s will provide you with more fuel earlier in the rpm range. This allows you to dial in more boost down low, allowing for more low end torque, reach your peak power sooner, and hold that peak power for longer.  The Nostrum HPFP kit requires no permanent modifications, allowing you to revert your vehicle to stock in the future. Being that these pumps are installed just like the OEM pumps, the installation is far less involved than a vacuum pump style kit. 

Our pumps are completely ethanol compatible, giving you the added benefit of being able to run e85 or blended ethanol fuel. Ethanol is wonderful on turbo cars, as it has a higher octane rating and is less prone to knock than 91/93 pump gas.  

Every Nostrum manufactured part is backed by a limited lifetime warranty. Our products are comprehensive solutions that come complete with everything you need inside the box, including detailed installation instructions. Tuning guides are also available for your dealer or tuner. We have customer service and calibration engineers on staff to provide you with any support that you may need, from installation to tuning.
