Bosch Original Equipment (OE) engineers ensure the highest quality, performance and durability in the development of diesel aftermarket parts. Meeting OE requirements takes a lot of effort, but we believe superior quality is worth it. We call this "The OE Difference."

 

 

The Bosch OE Difference is based on the foundation of delivering aftermarket parts that provide the Form, Fit & Function of the original parts.

Non-OEM Approved Remanufactured Product Testing

Bosch recently tested and evaluated numerous remanufactured or rebuilt common rail fuel injectors available in the market. The Bosch team used a state-of-the-art Bosch EPS-815 test bench with Bosch patented Shot-to-Shot (SST) functionality and on vehicle testing using the EPA testing protocol.

More than 50 percent failed, and presented a significant hazard to the engine if installed in a diesel common rail system. These hazards included:

**If you are experiencing any of the above, you should get your vehicle diagnosed and possible get your injectors tested.

One failed injector could lead to complete engine failure!

Following the testing Bosch also performed an injector tear-down for inspection and found that many of the components removed from non-authorized injectors were outside of the original design specifications.

used part with discoloration and corrosion

 

The manufacturer inserted a used part that has discoloration, corrosion and pitting. This can cause friction during movement of the valve piston, which can compromise the performance.

 

Non-OEM Approved Remaunfactured Products

The quality of any remanufactured injector depends on the remanufacturing process and components. During our testing process, we have found that many of the components removed from non-authorized injectors were outside of the original design specifications and some had corrosion and pitting, which compromises performance.

You might get a great deal on these non-OEM approved products, but you are taking a huge risk that these injectors may not be better than the one you are trying to replace.
