Subaru STI Injector Install

Subaru STI Injector Install

Not quite sure how to install your injectors? Neither was I so let me make all of the mistakes for you so that you don’t have to. We installed a set of Cobb 1050 CC injectors onto my 2017 Subaru STI with great success! Have any questions on what we did? Shoot me a message!

Bought some hitachi injectors that came with lower seals and fuel rail o’ring is there another seal that goes between the block and injector?

Jump'en Jack Flash says:

This video is old and I don't know if you'll remember. I didn't see you use any lubricant on the o-rings, do you need to use lube? If so what do you use?

malik abbara says:

Hi, hope you are doing well. I would like to ask you for STI 15, to get the performance of COBB NEXGEN STAGE 2. Will it be enough AEM 340lph, 1050X, and the maps on their website to hit 310 hp, or what else do I need? Thanks.

Nam Truong says:

What crushwashers did you have to swap out when you did this?

Wrx.lxrd_ says:

I’m on stock injectors, I have Cobb 1050cc do I have to get a re tune for that if I put them on? I also purchased stock injectors but I don’t want the Cobb ones to go to waste

lotsofkgmanable says:

You ever go back and watch your old videos?

Barbados Turf Club says:

Hi Smeedia, nice vids, but a crazy question, do you still have the oem ones?

GKclips says:

sorry to reply to an old video, but if i run full bolt ons (minus headers), will i need upgraded injectors? (i will have upgraded fuel pump) many people say you do not need for a stage 2 setup for my year (11-14 sti).

Isaac Mejia says:

Hey bro did you buy the pig tails separate or did it come with the injectors?

Ivan Humpedinbutt says:

Anyone know the torque spec on that banjo bolt? I can't seem to find it anywhere.

Samuel Mueller says:

Hey, great video but I'm having trouble following along doing putting my 1050 injectors in – I believe I've taken the right bolts (middle and left) out and the bolt on the right loose but not out, to move that shield to get to the banjo bolt, but that shield won't budge at all for me, am I missing something? On a 19 sti

Shane Bleskan says:

Hey tanner i know this is an old video, but with the banjo bolt, there is a hole in the center, how do we make sure that is all lined up correctly? And also same with tgv motor, how can we tell if the motor is on the gears?

Robert Blanchard says:

Are replacing the injectors enough to go to the stage 3 tune, or do I need to upgrade the fuel pump , rails, and new fuel lines? I ready have cobb intake, downpipe, and exhaust.

rhd em1harris says:

Rare chance you might see this. But my car had tons of fuel in the oil, and throwing codes p0011. Could a stuck fuel injector cause this

b g says:

you have to put that bolt back in it helps hold your rail in place.

bivensrk says:

Awesome video, as always! I have a 2013 WRX. Running a PW Verticooler, Cobb SF box, Nvidia DP, electronic boost controller, turboXS CB. Stock everything else. What on the AP can I look at for lean vs rich on fuel? Thanks!

Gavin Hawk says:

So you take out all the old o-rings and don’t reuse correct? The Cobb 1050x I bought didn’t come with a new separate set of o rings unless the SUPER SUPER thin rubber seal attached at the very bottom of each injectior is the “new” o ring. Can you help me out?

Brandon Hedges says:

Currently looking to replace my injectors as I have sporadic rpm jumps when driving. Is it safe to consider cobb injectors if I'm running just a stage 1+ SF tune with an intake on my 2012 WRX or should I just stick with OEM for now?

Brian Conover says:

Why or why not go with tgv deletes? I was thinking about removing my intake manifold so I could also have an easier time with the turbo inlet hose and another video I watched someone else did the tgv deletes. Any pro's/cons to doing that?

iRONIK says:

So I got the 2021 STI…any recommendations before I brake my car doing this?? Appreciate your videos. They have helped me almost have the courage to not pay someone or a shop. I want to do this myself but scared currently. Baby steps?

Michl Dehpunkt says:

Since the video is pretty old you probably already know what the the banjo bolt you removed is for. In case someone wonders: it is part of the AVCS system of the intake cam and the blue connector next to it connects to the AVCS control valve for that cam and is held in place by the normal bolt next to the banjo bolt.

henry Sanson says:

Do you need to tune after switching to after market injectors ? I think one injector is going bad on my Subie. I wanna future proof my car for mods

footballfan says:

Having a misfire on cylinder #4 no blue smoke coming out or weird sounds like knocking. I changed spark plugs ,but not coil packs or injectors. Was wondering your thoughts . Thank you 2010 sti with 106640 miles.

Erik Aaviden says:

Hi, my driverside injector is leaking air from the engine side and i cant get to it because of the shield.
My question is how you got the rear bolt off the shield? I can´t seem to get to it, any advice?
