Grams Performance 1150cc Fuel Injectors 02-14 Subaru WRX / 07-20 STI / 07-11 Legacy GT / 04-13 Forester XT / Outback XT 2007-2009

Part #: G2 - 1150 - 1200. Each injector is individually balanced, flow - tested, and precisely matched to ensure a difference of less than one percent among them. It's then pressure - tested up to 220 psi for leak - free operation and top - notch performance. This results in excellent cylinder - to - cylinder consistency, even at low pulse widths, and great idle quality, response, and overall performance. The ultra - fast and precise solenoids in Grams Performance Fuel Injectors have a linear response curve across a wide range of conditions. They can accurately measure fuel even at high pressures and short pulse widths. These injectors are cold - cut with diamond grinders in under three seconds for high precision, without the need for 'pre - seating'. Unlike competitors, abrasive cutting that generates heat and causes poor spray patterns is avoided. Each injector comes with high - quality Viton O - rings that can withstand extreme temperatures and harmful oils in some fuels. Every injector set includes dead time compensation values to maintain consistent air/fuel ratios during tuning. Grams Performance Fuel Injectors are rigorously tested in controlled lab settings with advanced equipment and on dynos, streets, and race tracks to perform well in extreme conditions. Features: High - impedance design without a resistor box, cold - machined tips for precise operation, ultra - fast solenoids for accurate fuel metering, linear response across various conditions, all injectors balanced and matched within one percent, compatibility with all known fuels like gasoline, methanol, and ethanol, and unmatched cylinder - to - cylinder consistency with optimal idle quality.

Using these Grams Performance Fuel Injectors is straightforward. Just install them in your Subaru vehicle according to the standard installation procedures for fuel injectors. Make sure to connect them properly to the fuel system. When tuning your vehicle, refer to the dead - time compensation values provided with the injector set to ensure the best air/fuel ratios. For maintenance, regularly check the Viton O - rings for any signs of wear or damage. If you notice any leaks or a drop in performance, it might be time to inspect the injectors. Keep in mind that these injectors are designed for high - performance use, so avoid using them in situations where they are not rated. They are compatible with a variety of fuels, but always use clean and appropriate fuel to ensure long - term performance.
