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!

New Bosch Armature


Armature The Armature works in tandem with the solenoid to regulate the opening and closing of the ball on the sealing surface. Each injector is carefully inspected and replaced with a brand new originally manufacturer armature.

Armature removed with corrosion


Armature Armatures in other injectors are repaired by varnishing and cleaning up the armature. This leaves behind corrosion which leads to inconsistent operation.

 

 

Valve Body new sealing surface reground to remove wear


Ball Seat (Top View of the Valve Body) This ball seat/ sealing surface is critical for injector performance. Abrasive contaminants can erode and damage the ball seat causing the ball not to seal properly, leading to improper injection and hard start conditions.

New Bosch valve body


Ball Seat (Top View of the Valve Body) The sealing surface/ball seat has been reground to remove wear, impacting the overall injector performance and reducing its service life.

 

 

New Bosch valve body

Valve Body The valve group is among the components which the greatest demands are placed. The valve group is directly responsible for actuating the nozzle and releasing the correct amount of fuel to be atomized in the combustion chamber. OE quality tooling is required to achieve the one to two micron tolerances needed for this precise component to operate properly.

used part with discoloration and corrosion

Valve Body Other brands insert used parts that have discoloration, corrosion and/or pitting. This can cause friction during movement of the valve piston, compromising injector 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.
