The B58TU HPFP upgrade kit for the N20 is the perfect upgrade for users wanting to run E85 on their N20 or have a larger turbo flowing enough air to max the stock N20 HPFP. 

Avoiding upgrading your HPFP and trying to run the Stock HPFP at its maximum capacity can cause the Stock HPFP to crash, which can cause engine damage very quickly. 

Save yourself a nightmare and upgrade to the B58TU HPFP.

As of 13 MAY 2021 due to demand for this pump in other markets, suppliers have increased pricing, as a result we have had to increase our pricing. This only affects this kit and not our other kit that does not come with the upgraded HPFP. We apologise for any inconvenience. 

This kit comes with the following parts: (Assembly Required).

  • Bosch HDP6 (known as the B58TU HPFP).
  • "Aeroflow 200 Series 3M Teflon Black Braided Stainless Steel Hose"
  • "Aeroflow 200 Series Hose Adaptor to -6AN Black Aluminium Fitting"
  • "Aeroflow 200 Series Hose Adaptor 150 Degree to -6AN Black Aluminium Fitting"
  • "Speedflow -6AN to Female M14x1.5 Inverted Flare Aluminium Anodised Black "
  • "Aeroflow 5/16 EFI Quick Disconnect to -6AN Black Aluminium Fitting."
  • Modified Valvetronic Valve cover seal plate. (OE 11377502022) 

Pre 11/2014 cars will need the Wiring harness adaptor and will need to splice into the factory harness to accept the new style electrical plug on the B58TU HPFP (HDP6), all N20's built After November of 2014 will have the new plug. Whilst there are some cars before November 2014 that did manage to get the newer plug from factory we cannot guarantee this to be the case for you and will offer the wiring harness plug to all customers who proceeded to have a car before 11/2014. If you're not sure what you have please purchase based off the Build date of your vehicle.

This kit is for those that prefer to fit a cheaper used B58TU HPFP (HDP6).


With regards to tuning E85, Rail pressure needs to be minimum of 24mPa and a max of 25mPa at 5000 - 7000 RPM. 

Significant Injector adjustments are also required to get the N20 to operate correctly on E85, consult with your tuner. 

For people running 93, leave the rail pressure 20mPa unless you are starting to hit the injector limitations.

This pump is rated to 35mPa (5000PSI), however going over 25mPa (3600 PSI) is not advised on the N20 fuel system at this stage. 

The part number for this B58TU HPFP (Bosch HDP6) is: 
BMW 13518631642
Bosch 0261520521

  • Please note: Improper installation can damage engine components or the engine itself. Whilst this pump is 90% plug and play, Navardi Tuned holds no responsibility for the installation, form. fit or function of this pump and any tuning this pump may be used in. By purchasing this kit you understand it is your sole responsibility to use this kit appropriately.
  • An important note, the Hard-Line from the HPFP outlet to the fuel rail is angled slightly off, whilst we have not seen any performance issues due to this and the pump bolts up to the Hard-Line just fine with no leaks, if you would prefer to have it aligned properly you will need to bend the Hard-Line slightly.
