WHAT CCs' are these

[Turbizmo]

I got some injectors from my school and I don't know if there low impedance of high impedance. In the bag that they where inside they said 290cc injectors i searched on Google and cant find nothing i don't even know if there 290cc and i don't wont to put them on without knowing these are the numbers they all have (60B7) thats on one side and on the other they say this (KEI KHIN or i this it says KEI HIM) a need help

If they are indeed 290cc/min injectors, they're probably high impedance. I've not seen low impedance injectors that small.

Here is a link to injector data sheet.

I don't see any 60B7 on there and don't know what else to look for, 290cc is 17.4 L/Hr which I don't see anywhere either although it is within their range.

I would say they are probably high impedance as all the injectors on 2nd page are(1st page not sure but probably are all high impedance).

I would say to talk to them but

Keihin does not have a direct sales channel for aftermarket products. Keihin has arranged with our distributors to offer support to individual customers for these products and purchases. Please refer to our aftermarket distributor list for contact information. Also, products and technical support for components that come as original equipment on vehicles is available from the product dealer or manufacturer. Unfortunately, Keihin is not able to respond directly to requests of this type for support.

I would say you are safe assuming high impedance.

I heard that you can distinguish LOW and HIGH injectors with a VOLT meter if its lower that 4 there high and if there higher than 4 there low is this true?

If they're lower than four ohms, they're high impedance? How does that make sense?

You can't test the injectors with a voltmeter, but you can test them with either an ohmmeter or a multimeter. As I think you were getting at, anything less than four ohms is generally considered low impedance, whereas anything greater than four ohms is high impedance.
