I just got some Injectors in trade but I'm not sure if they'll work because they seem to be missing the plastic peice that holds the o-ring where the injector meets the manifold...
Also, do these look like denso's? the only markings are a hand engraved "089" right below the o-ring where it goes into the fuel rail and also "220" that is molded in the plastic on the side where the harness clips on... I'm just curious because the member I got them from didn't seem to sure about them and he has been so busy that he hasn't gotten back to me about an email from wednesday.


you can see whats missing here



EDIT: Do I just figure out how to pull that part off my other injectors and press it on these? it to have a metal peice with 4 little holes and the size of those vary with the size of the injectors though don't they? I Know the little holes in the tip of my 42#ers and bigger than the stockers...

This is really important... A member was expecting me to ship my injectors to him tomorrow but now I must return to school and won't be able to work on my car again untill next weekend. I need to know asap so I can send his back if I can't use them...

The injectors you received in trade are DSM style injectors. That is how they fit the 4g63. The look like automatic injectors as well which are like 390cc if i recall. Thye are also low impedance.

Thanks for the responses, much appreciated!
