Siemens 668cc High Resistance Fuel Injector with 11mm Top O-Ring

These injectors flow 60 lbs/hr at 43.5 PSI ( 3 BAR ) and up to 85 lbs/hr at 87 PSI

In addition, these units are high-impedance so no need to add ballast resistors making them compatible with most engine management systems.

Despite the high flow rate, they are linear and controllable at low pulse widths and have been used in ULEV applications! This allows you to use a larger injector than normally possible without hurting idle and low speed driveability.

These injectors can function at high fuel pressures and don't exhibit the high fuel pressure handling problems found with many other high flow high-impedance injectors. This makes these injectors very well suited to turbocharged and supercharged applications that see high fuel system pressures.

As used by the Toyota Racing Series for all cars for the 2008, 2009, 2010, 2011, 2012 and 2013 seasons running E85 ethanol.

Fuel battery compensation / dead timetable supplied with each set of injectors - makes tuning a lot easier.

Ideal for use on many Japanese engines including the following:-

• Toyota 2JZ, 2ZZ, 3SGTE
• Mitsubishi Evo 4G63T
• Nissan RB26, SR20, RB25

Dynamically flow tested in New Zealand by us, so that your set of injectors is matched within 1% across the entire set.
