Hello i need help to identify these injectors.
So they are all low imp square orange with part number 195500-1350 out of an 1986 Fc NA 150HP
But in the forum and everywhere else the orange ones are 195500-0900 so im a little confused
I have 2 exact same 13b’s and i mixed up the injectors All of then are 195500-1350 but
I have 4 with “532” on the side of the plug and 4 with “624” are the 624 ones the primary bc they are supposed to be a bit bigger or is this nonsense?
In the second image is the 3 digit number
Sorry for asking stupids questions Thank you
Did you measure the impedance? If not, than I would recommend using a DMM and measuring the resistance across both terminals. Low impedance is 1.7-3 ohms and high impedance is 12-16 ohms. It's the 195500-1350 number that matters. That's a Denso part number. Mazda changed from low to high impedance injectors sometime in 1987. From what I could find, that p/n looks to be 87-88 high impedance injector.
In reference to your 2nd question. To my knowledge all 2nd gen n/a cars used the same size injectors in the primary and secondary positions. Turbo cars used bigger injectors that the n/a cars 550cc vs 460cc for n/a but were the same size for primary and secondary as well.

okay i will measure them to be sure tomorrow.
But isntthe difference in the little notch on the plug if they are low the notch is in the middle and if the notch is little ofcenter its high imp?
Thank you

High and low impedance injectors would have different part numbers. The notch on the connector would be associated with that specific part number. In other words, you're not going to get one part number injector with two possible configureds of connector.

Nippon-Denso p/n 195500-1350 both have the same flow specification (460 cc/min @ 43.5 psi), but can be either high or low impedance depending on the connector color. Yours look to be red, so that injector is low impedance for 86-87 RX7 non-turbo.
Thank you
