OEM Bosch Fuel Injectors Set (6) for 1997-1998 BMW 528i 2.8L I6 97 98 2.8

Item Description The ECU controls your injectors as a set. So if they are imbalanced at all, you will have some cylinders that are flowing slightly rich and some flowing slightly lean. The percentages are how closely the injectors are flow matched to one another. The closer that the injectors flow to one another, the more precise the entire fuel system will be which makes it more efficient. This improved efficiency manifests as better fuel mileage and a smoother engine. We offer an advanced 1% flow-matching service which also includes documentation of the flow-results for each injector. This is $80 for the advanced flow matching. As far as which option is correct, the choice is entirely up to the customer based on their individual needs and budget. Our state-of-the-art factory uses only ASNU flow benches in our certified ASNU service center. Our flow technicians are ASE certified Master Mechanics, so you can feel confident that your fuel injectors are being tested and rebuilt properly.  Our goal since starting this business is to provide top quality auto parts to customers at a fraction of the price that they are at local auto parts stores.  This is what has driven our business to success, and what keeps us going in this increasingly flooded market. Genuine OEM Injectors VS. Chinese Aftermarket Parts: With the recent flooding of Chinese knockoff injectors that have reached the market, it has become increasingly more important to separate our factory and products from the competition. When comparing a rebuilt OEM fuel injector with a "brand new" Chinese knockoff injector, the rebuilt OEM injector will always come ahead with a closer flow-match, precision laser cut nozzle plates, better atomization, and reliable functionality for years as opposed to days. If you have any questions, we are very happy to discuss the products we sell. Please do not hesitate to reach out to us. ``` Advanced Flow-Match #### Advanced Flow-Match ```  All of our sets are flow matched to 3-5% or better (OEM factory standards).We offer an advanced flow matching service with documentation for $80 for 1% dynamic flow match with documentation The percentages are how closely the injectors are flow matched to one another.Static flow matching involves testing the injectors at 100% duty cycle.Dynamic is the process of testing and matching the injectors at all duty cycles.
