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


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

With Function characterized by the
following key criteria:



OE Performance Circle

OE Performance

The Part performs functionally
as the original part did

OE Reliability Circle

OE Reliability

The Part performs as the original part
did regardless of any condition

OE Durability Circle

OE Durability

The Part lasts
as long as the original part did

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

One failed injector could lead to complete engine failure!




Tear-down Findings from Bosch Testing Process

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 OE product

Non-OEM Approved Remanufactured 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.
