Most of the site isn't even done.
The FID 1100's are Bosch EV14 based High Impedance fuel injectors utilizing the latest in fuel
injector technology. They come in sets that are matched within 1% static (I.E. Full Flow) and
2% dynamically (I.E. being pulsed). This matching process provides great cylinder to cylinder
consistency. The matching process combined with the fast response and linearity of this injector
produces amazing idle qualities, excellent drivability, and smoothness not found in other injectors
of this size.
Also, what you thought; it's "Injector Dynamics" (ID)? Not really Fuel Injector Dynamics?

They're also made Bosch based.
The FIDs you got, if you wanted to go by description and performance, you got better
ones because they're matched sets.
