Recently, some repair shop customers have been purchasing ‘brand x’ common rail injectors somewhere else, because they think the OEM product is too expensive. What is the reason for this discussion? The ‘brand x’ injectors did not work. This does not mean they did not run the engine (although in one case, they really did not!). This resulted in their customers (the truck owners) being unhappy. The little bit of money that was saved by buying a cheaper injector was soon forgotten, after tow trucks, smoke, low power, poor economy, and repeated visits to the repair shop.
Bosch (the OEM manufacturer of most common rail injectors in the market today) recently published some test results about the ‘brand x’ injectors. First, they bought a used pick-up truck. Then, they dyno’d and tested the truck with genuine injectors, and recorded emission levels, soot, and fuel economy stats. Out came the genuine injectors, then they installed ‘brand x’ injectors. The same tests were conducted and results were recorded.
That is assuming the injectors that were purchased last that long, and did not cause any other issues. Needless to say, the repair shop customers mentioned above will only be buying genuine Bosch injectors in the future!
