Title: Bosch nozzles
Post by: ToddA1 on April 25, 2011, 07:48:40 pm: Putting an order together with Rock Auto, and I notice an odd p/n with the nozzles they carry.... BOSCH Part # 0434250103 for $11.11 each. Most other online sites list Bosch p/n: W0133-1632076... lowest price I found was $12.95 each.

Anyone have any experience with the 103s? Maybe Rock Auto's p/n were superseded, and they just have old stock? They're both listed for my '81 CR, but I just want to make sure before I place the order.

Post by: Mark(The Miser)UK on April 26, 2011, 03:17:40 am: I recently imported from Canada to here in the UK, 4 of these Bosch nozzles in an attempt to assemble 4 perfectly matched injectors. 8)

That part number was on the box. Made in France DN0 SN 293's. Seemed genuine old stock. However I broke one ::), two were perfect, and one has a needle too loose to operate correctly. I found an old needle which has which a better fit and a popping spray pattern.

The Bosch code 0 434 250 103 referrs to the 293's, but so does 0 934 002 870
and 0 934 001 850, so does the code refer to alternatives, older issues, or other.

More importantly does the code always refer to the same manufacturing period, and potentially help the search for older better quality?

Having said that my nozzles at best were 75% acceptable.
Was there a drop off in French quality which led to Bosch switching to India, or was it purely monetary?

Thanks.

The DN0 SDN293 is the model/style type of nozzle as designated to 1.6TD engines. The 1.5 qnd 1.6 engines used DN0SD193 style. However they are entirely interchangeable
