Item Condition: Manufactured Again

A properly “Manufactured Again” injector is the functional equivalent of a new part, and is virtually indistinguishable from new part performance. Manufactured Again takes products through a restorative process, using highly refined industrial procedures in a factory setting to promote greater resource productivity, and aims to reduce waste and avoid pollution. It is the only form of reuse, re-purpose, repair, or recycle that produces warranted products that meet or exceed quality and performance expectations. 

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

Every 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 manufactured again components.  After full disassembly is complete, the part is reassembled and tested for compliance with OEM Bosch performance specifications wand may be retested with our patented 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. For more info on the NEO click here.

Dieselogic was a great place to deal with, the person was nice, the thing I really liked was I'm a do it yourself guy and a lot of the times when you call and ask questions people want to make you feel stupid for the questions you asked and don't want to deal with you but Dieselogic wasn't like that. they were very helpful and got me the kit I was looking for at a good price.
