RE: Fuel injector details-
Reading further into this it seems RockAuto has some issues getting more than just one or two in stock at a time, and they appear to sell pretty much instantly. For their pricing it's worth checking them out, but don't be surprised if they aren't available or they don't have enough in stock to meet your needs.

So, I pulled some data from ECS to provide a baseline for pricing and part numbers. I'd encourage shopping around and if you can find a better price from a place you are comfortable giving your credit card details to, then by all means get em!

And, I'm a noob here still. This info should be correct- hell, it's what I'm filing away for my own use. That said, if I've borked something up please PLEASE speak up so correct data can be had!

It is recommended to replace all six instead of mixing and matching. Vehicles with old injector 7585261 will need to inspect their existing injectors to determine if these can be replaced individually. With an index of 11 or greater, injectors may be replaced individually with a new injector. If the index is 10 or less, all 6 injectors must be replaced. See pic below for index number location.

Replacement also requires 13537564751 for each injector.

In the pic below the index is found after the part number. In this example the index number is 11 (13537585261-11)

The N55 platform doesn't seem to have the same injector issues that the N54 does, but with these prices it doesn't really matter.
