Anyone have a detailed write on swapping out the OEM injectors with new OEM ones? Also, anyone know how much/where to buy a set of 4 besides the dealership?

I took off the fuel rail and cleaned the injectors and re-installed them.

Did they pop out pretty easy?

Was your car running bad or did you just do it as maintenance? Curious about how dirty they were.

Did you replace the black Teflon seal (or what ever those are made from)? If not I would advise pulling them again, because once removed those seals are suppose to be replaced with new one before reinstall.
edit: Clean them with what though? You would be better off spending the $200 to ship them to a company to have them flow tested before and after, pattern spray charted, etc along with a proper cleaning to ensure they are all up to par imho.

I took the time to clean them myself. I used a very gentle solvent to clean the shaft of the injector, over-lapped the black gasket's with tape after. Used brake cleaner for the tips with a tooth brush and magnifying glass to making sure none of the tiny holes were blocked by bigger partials. this took me a bit to do, I was going slow.
I do not plan to take off the fuel rail again unless I want to replace the seals. Did I replace them after the first uninstall? No, no need to. (IMO.)
The fuel accessory was simple to uninstall.
The car was not running bad at all, It blew a piston in cyl. 1.(then it ran bad) Since I took out the whole engine block, I went OCD and cleaned the whole thing plus parts.
After the piston blew, and I took everything off, oil had gotten everywhere and the whole system looked like it had over 150k miles on the engine, when there was only 37k on it.
Be very careful when in the process of taking out and putting back in, do not force anything, and always clean again when reinstalling (wiping any dust off) You do NOT want to put any gouges into this system or you'll be sorry.
I hope this vague write up is understandable.

Bump anyone??
Down and dirty how to.
Pull the low pressure fuel pump fuse. Top left on the fuse box under the glove box.
Start the car and let it die. It's going to take longer than you'd think.
Remove the intake crossover and air box
Remove the intake. There should be some other guides on how to do this.
Completely loosen the large but on the fuel rail.
Remove the bolt holding the fuel line between the high pressure pump and rail.
Loosen but don't need to disconnect the nut at the high pressure pump.
Disconnect the fuel rail pressure sensor.
Remove the 4 bolts holding down the rail.
Pull the rail straight up to remove the injectors. Might need to wiggle them out.
Clean the injectors holes on the head.
Reinstall is the reverse but you need to push the injectors as far down as you can before starting to use the bolts.
Torque the bolts down to 10nm starting in the middle and working out from there. Do it in steps as it's going to slowly draw the injectors into place.
Completely loosen all bolts.
Tighten all bolts in the same order as above to 20nm
Put everything back together.
