Get rid of your misfires forever! - BMW E90 DIY Fuel Injector Upgrade

The fuel injectors on the N54 engine were ahead of their time piezo-electric high pressure injectors and they never worked right and were prone to clogging and leaking.  It took BMW 12 iterations to get it right (and the jury is out on whether they really did but it's the best we have at this point!).  I finally found some index 12s on a car in the junkyard (my sponsor is still out of stock due to the pandemic!) so it's time to install them on the car.
