Injectors 550 CM871.

[Rawze]

I would suggest only going with genuine certified new or re-mans.


not worth risking a $36,000 engine because of a bad spray pattern, etc.
here is my take on used/reman injectors...

that is just my own opinion on it any ways.

also, you cannot just slap in different size, or incorrect part# injectors,.. make sure what you replace is the same part number that your engine requires.

Also, if your getting an inframe done, your concerns should also be ensuring you have that engine counter-bored + liners raised to 0.014" - 0.,015" , and all the other things recommended on this forum ... otherwise, you could be doing it again in a year or 2. -- Too many shops out there that can't build an ISX worth a damn any more these days... Especially the OEM stealersh$its and OE cummins shops, they seem to be the worst for engine re-builds with all their garbage-can certifications
