            -All upgraded Products ARE Remanufactured and not refurbished.

Upgrades include premium Remanufactured & tested/calibrated LB7 injectors using only OEM (original equipment manufactured) Bosch cores.  These injectors are the latest revision and up to date OEM specifications required by Bosch to replace the original generation legacy LB7 injector.


The definition:

A properly “remanufactured” injector is the functional equivalent of a new part and is virtually indistinguishable from new part performance. Remanufactured is not refurbished nor used. 

Invest in a quality product instead of being misled by false representations of a “quality” remanufactured injector.

Every upgraded injector is completely disassembled, cleaned and 100% of all parts/components examined for wear and breakage. Worn out, missing or non-functioning components are replaced with new or rebuilt components.  After full disassembly is complete, the part is reassembled and tested for compliance with OEM Bosch performance specifications with the Dieselogic NEO.

NEO– resolves complex “shot to shot” Multiple Injections with Dieselogic Patented Fiber optic technology. The NEO provides validity testing of Common Rail Injection internal calibration emission tolerances, and stimulates the aftermarket economy while lowering emissions for a greener environment.
