WTF are these fuel injectors?
 

They were advertised as RX7 460cc red top injectors. The clip is square, as opposed to the rounded Miata ones. The Miata pintle caps are too small.

Part number 195500-1350.

EDIT: Clips look just like these:

EDIT2: Ok, after some research here (http://www.witchhunter.com/injectordata1.php4) they are, in fact, from an RX7 and they have hte same clip, but came in both high and low impedence. How do I tell which ones I have?

If you have a multimeter measure the resistance between the two pins on the injector where the connector goes.

I always thought the square clip was the low Z ones.

The low-imp are 470cc.

the high impedance ones are notched differently than the low, on the plug, i think ones lower center, and ones offset or something, i forget....

Don't take any thing for granted. Check them so you know.

+1 it takes 3 seconds to check. hi-z is > 10ohms, low-z is < 4ohms :)
