I have a 82 300 SD and I work on the road A LOT!!! I have a set of kermadi injectors that I recieved a long time ago and my question is were they any good???I have been wanting to put them in and now I have time. Is there any body out there that can let me know if they turned out to be any good?

Is this the place that they came from? http://www.kermatdi.com/servlet/StoreFront
The above company sells Fartelli Bosio Injector Spray Nozzles but as far as I know not the complete Injector.

And are you talking about complete Injectors sold by them or are you talking about regular Mercedes Injectors that have had Fratelli Bosio Spray Nozzles installed on them in place of ths stock Spray Nozzles?

I will have to take them apart and put the new nozzle in

There still in the box and the name on them are Bosio

Bosio nozzles are good quality.

Bosio Nozzles have a good rep.
The site below "How to Rebuild Injectors" should give you a good idea what needs to be done; with the exception that I think the parts should be lapped on a real lapping plate or at least a glass plate insted of putting Emery Paper over the glass. I also believe they should always have their opening pressures set on a Pop-tester/Nozzle Tester.
There are 2 members that will rebuild your Injectors at a resonable labor charge if you supply the Spray Nozzles. Unless one of them happens to live near you you will need to ship the Injectors to them and pay the return shipping. So you will not be able to use your car during that time.
