Well, my injectors are also leaking, and I looked around, seems like the best way is to have em rebuilt. I called napa, and they wanted $220 for remans (per injector)
...Not long afterwards, I remembered this place:

$35 for rebuilt injectors? Holy S***!
UPDATE: Here's another place I found!
A set of 4 remans would be $200, and a Cleaning and Flow Testing would be $65
