I am thinking of replacing the Injectors on a 89 Max SE. anybody knows what the difference between black marking and blue marking injectors?

thanks for the reply.

 

Just keep all of them the same color

 

don't mix and match color codes. and only buy new on those in particular

 

black and blue injectors can be mixed. there is no difference between them besides the damn dot.

 

if theres no difference why would they go thru the trouble of making them different colors ?

 

UMMM wrong!
Bosch doesn't make 2 different parts #s for no valid reason.
There is a difference between them. Just can't recall what it is at the moment (dam senility)

 

my friend has both black and blue injectors in his 91 brougham and his car runs like a dream. i would just be cautious of running ve an vg injectors together though.
but if i'm wrong someone tell me why so i don't end up making a mistake with my injectors....bah the blue dot is what i use and i already have two extras kicking around, so i'm cool.

 

Black can always replace blue
Blue shouldn't replace black
the difference between them is a bit o' resistance
running VE and VG injectors together is a nono different flow rates.

 

Nissan Engineers were smokin' crack man!

 

actually bosch's engineers were. Hence the BS sidefeed design.
