Fiveomotorsport, Newest Technology, Bosch EV14, 550cc High-Performance Fuel Injectors

  • List price includes one (1) fuel injector with Plug and Play adapter
  • Long Import Fit:  Mazda, Toyota, Lexus, Mitsubishi, etc.
  • Flow balanced and matched sets available when ordering multiple injectors
  • Aproved for use with all fuel types


FLOW CHART: sold with a complete and unique flow-data chart indicating individual static flow rates at 3.0, 3.5, and 4.0 BAR. As well as 3.0 BAR dynamic pulse testing for idle (15% duty-cycle) and 50% duty-cycle. Along with a complete dead time off-set (latency) table. Flow matching was done with industry-standard equipment of the highest quality.
The tests were performed at varying temperatures to achieve realistic results. Linear tuning with excellent low-end, and idle rpm.

Flow rates:
52 lbs/hr, 550cc/min at  43.5 psi (3.0 bar)
57 lbs/hr, 600cc/min at 50.0 psi (3.5 bar)
62 lbs/hr, 649cc/min at 58.0 psi (4.0 bar)
Dead Time (latency): 0.455 ms at 14 volts

High resistance, no inline resistors or resistor box requires for use.
All New-Generation EV14 fuel injectors will function at rail pressures in excess of 101 psi, 7 bar.

Excellent low pulse width response with predictable response down to 1.5 ms.
Excellent atomization for modern multi-valve engines.
This set will require no more than a 1% trim for easy tuning.
