BMW Fuel System Parts

Includes a full set of injectors (13538616079 x8), seals (13537584315 x8), and decoupling elements (13537564751 x8.) Why replace a full set? Fuel injectors are indexed, meaning they have to be replaced with injectors of the same index number and are not recommended to be replaced individually. This kit addresses the issue with 8 new injectors and decoupling rings.

More on injector indexing:

The index number is found on the head of the injector after the BMW part number.

Example: 13 53 8 616 079-11. "11" is the index number.

Injectors with index 10 and lower have a different calibration and construction than injectors with index 11 and higher. Because of this the injectors with index 10 and lower cannot be mixed with index 11 and higher in the same engine.

*Brand new HPFP - No Core Charge!*

The High Pressure Fuel Pump (HPFP) is a point of weakness in many BMW engines and fuel systems. If this goes it will prevent your car from running or starting due to fuel starvation. Restore your fuel system's operation with high quality OEM Bosch fuel pump.

Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer. Bosch has likely supplied many of the original electrical (and mechanical) parts for your BMW. Thanks to their quality, high durability, and reliability, you should expect a long service life from Bosch products.

As a leading source of high performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts.  All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

The Precision Raceworks G8x/G2x Stand Alone Auxiliary Fuel System is the highest-performing and most stable low-pressure fuel system on the market! Forget about how things have been done and embrace the benefits of dedicated fueling for your port injection!

Since direct injection came out for BMW, enthusiasts have been adding port injection.  With this came the need to upgrade the low-pressure fuel system to keep up.  Historically this was done by increasing the output of the main fuel system.  Unfortunately, the main fuel pump is controlled using PWM by a factory programmed controller designed to reduce output when target fuel pressure (typically 5 bar) is exceeded, creating a constant battle when pumps are added or upgraded.  This limits upgraded fuel pumps from performing to their full potential.

Additionally, the high-pressure pump control system dumps fuel back into the low-pressure system at high pressure low volume resulting in oscillations of the low-pressure fuel system.  Because of this, the DI system in the car is required to constantly make corrections to keep target AFR in check.

With this stand-alone low-pressure fuel system dedicated to your port fueling that is a thing of the past!  Get rock-solid fuel pressures at any pressure, run fuel pressures that are 1:1 scalable to boost pressure, flow more fuel with dedicated lines, run smaller injectors and still get more fuel than you did with large injectors (allowing for higher resolution), put less demand on the car’s DI system to correct for fluctuations in pressure, even your tuner will be grateful as the system makes tuning of port fueling even easier and more accurate, the list of benefits goes on and on!
