Hello guys

1. is there any link on how to remove the injectors on an sti v3/v4.

i could see they are yellow, if i was to upgrade them. Which ones would you recommend?

i am not looking for big power but since the current ones might be bad so are there any direct upgraded replacement ?

2. Fpr, i have a link ecu. Is there a fpr that has a sensor in it? I want to upgrade mine as it might be bad.

best way ti fit a fuel pressure sensor?

thanks guys

Really easy to remove injectors, just takes abit of WD40 and twist and lift I've found works best.

If your looking to do a cheap upgrade, you can go too V5 V5 440 injectors. They have a better spray pattern.

You can also get 550 yellow injectors. Both of these world need adaptor kit to fit in the V3 V4 fuel rail.

340 ish plenty for your gearbox leave them alone and you don't need a fpr at that level.
New pump, filter, plugs and air filter and away you go

Only one I'd upgrade to injector wise and that is the phase 2 injectors 440, with better spray pattern. ICP do injector fitting kit.
