$ 1,199.00

2013-2018 Ford Focus ST 2.0L

2016-2018 Ford Focus RS 2.3L

The entire fuel system is comprised of a low-side in-tank pump, a high pressure cam driven pump (HPFP) and, direct injection injectors. At low RPMs, the HPFP is first to run out. At high RPMs the OEM injectors run out of duty cycle (direct injection injectors can only spray for half the time of normal injectors because you don't want to spray during the power and exhaust strokes).

The upgraded XDI injectors flow 2000cc/min.

Compared to the OEM 1220cc/min on the Focus ST and 1320cc/min on the Focus RS.

With the pump and XDI injectors you will gain fueling headroom at peak hp. Consider getting the XDI HPFP for fueling down low or Aux Fuel.

This injectors require Pro Tuning.
