STi Injector top caps - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hello everyone. Just have a quick question. I have in my possession 8 sti injectors (of which I will eventually sell 4 and keep 4), but one of those sets are missing a black cap that is right on top. What are they called/do I need them/can I get them from my stock SR's when I replace them? They may be called insulators? Thanks in advance.

Here is a picture of the missing cap right on top.

Here is a circle around my other set with the black top cap.

I just looked at mine and I never noticed them before. haha. I always thought that was open for fuel to go in. I've never seen that cap on KA injectors.

Yeah when I noticed them I was confused. Wondered what they were or if they were necessary. I still have no idea what they are. So do u have injectors with them or without them?

with them on

n8RPS13 · 02-15-2012, 06:54 PM

Mine have them. I would call a dealer or get on a STi forum and ask around.

waxball88 · 02-15-2012, 07:02 PM

Mine also have flat tops

weirdchris555 · 02-15-2012, 07:06 PM

Thanks guys. So you just threw them with those plug things right into you're fuel rail? I kept searching and it seems like they are spacers of some sorts. Do you guys have SR's or KA's? I also read on KA-T that someone had sent theirs out to deatschworks and they removed those caps for his KA fuel rail.

waxball88 · 02-15-2012, 07:08 PM

You can put them in the rail you just take out the little spacer things the OEM ones use. I had issues with the clips. Just took pigtails off a legacy
kat pwr here

ATLspeed · 02-15-2012, 07:08 PM

mine never had them. Never had a problem

weirdchris555 · 02-15-2012, 07:10 PM

Yeah thats what I was thinking. If the stock one's have those spacers I was just going to reuse them. Did you repin them? I have the pigtails too, I was just going to try to repin them instead of cutting and soldering.

waxball88 · 02-15-2012, 07:15 PM

No way you could repin the plugs I have just soldered them in

Mitsubayati · 02-15-2012, 08:21 PM

Just solder them in. I plan to make a clip just in case

weirdchris555 · 02-15-2012, 08:36 PM

I have the clips. I may as well try to depin and repin them first. I am more worried about those spacer/caps. Thanks for all the info.

Ok talked to Witchunters and they said the caps were unnecessary. And on another note I found the caps burried in the box. Lol so this can be locked up.
