Some help with fuel injector identifacation

[kevin]

I bought 4-450 cc fuel injectors off of ebay.I just got them and they are almost clear topped or "opaque white" instead of blue.How can I find out what they are?I don't want to put a part that is questionable in my car.Thanks for your time.

Are they Denso's?? I'm not a fuel/motor guru, but I think the big issue (as long as they seat in the rail) is the impedance. Our cars run low-imp. injectors, put hi-imp in and I'm pretty sure its bye-bye ECU.
Let me ask the obvious, why did you buy 450's?????

The guy says their 450cc but the top color is off.I pay pal him and it took him 2 weeks 2 reply to "when will you send e-mail to him".He claimed on e-bay that he had them in his garage in bubble wrap for an upgrade but went with 550cc for his project.When I finnally got them they where shipped in a rag in a check box.All of this kinda stinks of something being wrong.
