All injectors are serviced on state of the art ASNU machinery.  Completely disassembled for penetration of dirt and deposits they are ultrasonically cleaned for multiple cycles.  Ultrasonic cleaning uses frequencies that create cavitation pockets which disappear as fast as their created and the solution literally blasts the deposits away on every surface of the injector inside and out.  Ultrasonic cleaning is done with proprietary formula to ensure deposits stay dissolved.  Backflushing is later performed where solids that weren't dissolved get rushed out the injector under pressure.  What you're left with is like new nozzles surfaces, now it's time to stress the injectors under simulated modes that mimic their operation on your vehicle.  ASNU is way better than knock off test benches as they offer a much wider range of duty cycles and speeds.  Injector coils which are not running like they should will fail these tests and this eliminates issues in the future that do not show up with cheap China test benches.  Sets are matched into bins with their corresponding flow rates, assembled, and packaged together to ensure you're getting the best set available.

I take pride in my shipping speed.  I will ship your injectors same business day in most cases but if it's late in the day it will have to wait until the next business day.  The earlier you order the better.  When you offer a great product at such low prices, workload fills up quickly and each order is shipped in the order it's received so don't wait!
