Subaru WRX & STi ('07&up)Injector Set (and fits '04-'06 STi with WRX tumbler conversion): 4 x 2150cc Saturated / High Impedance Injectors. These are the largest high impedance injectors available! These injectors utilize the latest technology to provide great linearity and short pulse width repeatability even at increased fuel pressures. These injectors do not require a resistor pack or P&H drivers. DO NOT USE WITH VP Import, Q16 or OTHER MTBE OXYGENATED FUELS
Fuel Injector Clinic injector sets are precisely flow matched to within 1%. Each injector within each set is individually numbered and results for each injector are listed on a detailed flow sheet included with the set. Dynamic flow matching is used only on injector sets where the additional time and cost are justified by the corresponding benefits gained during the tuning process.
Fuel Injector Clinic injectors are flow tested and rated at 43.5psi (3Bar) at 75??F average fuel temperature using CF-16B calibration fluid.
The superior spray pattern and atomization make these injectors easy to tune and provide great drivability.
Fuel Injector Clinic injectors are set up to and include all o-rings needed to fit the factory application for the listed vehicle. For aftermarket or other unusual setups please contact us prior to placing your order to make sure you receive injectors that fit properly.
Every injector is covered against failure caused by defects in original manufacture by our 12 month warranty.
Fuel Injector Clinic injectors use the factory electrical connector or include solder-in pigtails. You can purchase adaptor plug-n-play' harnesses to avoid cutting your stock harness as an optional extra.
This injector set contains high impedance injectors matched to the saturated injector signal generated by this vehicle's OEM ECU, OR is suitable for use with an aftermarket ECU made or set up for high impedance injectors.
This massive injector is in a class of its own when low-end throttle response and short pulse width control is required. Multi-point dynamic flow matching is used during the production of these injector sets due to their large flow rate which significantly improves the ECU's ability to control these injectors in the sub 2ms pulse width area )typical of idle and part throttle conditions.)
The internal construction of this 2150cc/min injector includes a seal that has been found to swell when in contact with MTBE from oxygenated fuels like Q16 or VP Import. This swelling causes a significant reduction in flow through the injector and therefore renders it unsuitable for use with MTBE oxygenated fuels.
