Bosch fuel injector differences

[Adrian_Visser]

Anybody know if there is any difference between a bosch 0 280 155 746 yellow body) and a 0 280 155 702 (black body)?

They both have identical flow ratings (208cc@ 3.0BAR) this equals 21.4lbs/hr@ 3.5BAR and 20lbs/hr@3.0BAR.

Funny thing is bought a set of the 746's which are yellow and slim bodied as 19lb'ers for my m20 and I am running them with no problems. Now I am shopping for injectors for my s52 swap and by the numbers I could use these injectors as they flow nearly the same as stock, the 702's have the same flow rating and impedance but are black bodied instead of yellow.

wtf?....

I've always found this page to be pretty helpful.

Based on the parts and information they seem exactly the same, just a color difference i guess, maybe one is older than the other?

Any idea what cars the injectors came out of?

Never mind actually upon further inspection I have 710's which are 14.3ohms and 210cc versus 16ohms and 208cc@ 3 BAR for the two I mentioned above.
