-hey guys new to this site, everything seems pretty cool so far. About my question. I've got a 92 NA 300 (prod. date 5-92) i need to replace the injectors, i ordered the blue ones (i read somewhere that my prod. date came with blue) anyway i just pulled off the upper plenum and pulled out a couple of injectors, and guess what? they were black. my question is whether or not i can replace all the blacks with the blue ones. I've read somewhere that the difference between the two is the spray patterns. i dont have a problem with returning my blue injectors so i can order the black ones. but i'm slightly impatient, and i miss driving my Z. i would assume that both injectors would have the same resistance value (10-14 ohms) but i'm afraid that one might flow more fuel than the other. and i rather not have my car running way too rich. thanks for any response.

as written at the bottom of the page.

Application:
Note: This injector replaces the FUEL INJECTOR (BLACK) - 300ZX 1990 to 1993 Non- Turbo
Note: This injector replaces the FUEL INJECTOR(BLUE) - 300ZX 1990 to 1993 Non-Turbo

so in other words you're ok with the blue ones. change'em out.

 

hey thanks alot. you saved me alot of time to wait for new injectors, i'll pull the rest out put in the blue ones.
