so i bought some denso 550 injectors off applesauce not too long ago. A couple of the plastic things that surround the nozzles are chipped/cracked. Are these replaceable or did I get effed in the butt? If replaceable where can i buy them? I didnt wanna try to remove it until I got some confirmation that they can be replaced relatively cheaply lol. used my phone to take a pic, idk if you can see the missing plastic, this was the worse injector.

No I am not talking about those, those are rubber by the way lol. And also on the other side of the injector. Theres like a rubber boot on the bottom of injector, and beneath that is the plastic piece that surrounds the nozzle thing. anyone?

They come in most injector seal kits. If you look at the pictures on Rock Auto for the injector o-rings they're included. I replaced all mine when I redid my head.

You don't want to burn a piston up. Did you know they were broken when you bought them?
