Grams Performance 1150cc Fuel Injectors Nissan 350z 2003-2009 / Infiniti 2003-2007

Part #: G2 - 1150 - 0700. Each injector is individually balanced, flow - tested, and dynamically matched to ensure they're within one percent of each other. Pressure - tested up to 220 psi, these injectors guarantee leak - free operation and top - notch performance. You'll enjoy excellent cylinder - to - cylinder consistency, even at low pulse widths, along with great idle quality, response, and overall performance. The ultra - fast and precise solenoids have a linear response across various operating conditions and can accurately measure fuel, even at high pressures and short pulse widths. Grams Performance injectors are cold - cut with diamond grinders in under three seconds for high precision, no 'pre - seating' needed. Unlike competitors, there's no heat - induced poor spray pattern. High - quality Viton O - rings resist extreme temperatures and harmful oils in some fuels. Each injector set comes with dead - time compensation values for consistent air/fuel ratios during tuning. These injectors are rigorously tested in labs and on dynos, streets, and race tracks for performance in extreme conditions. Features include a high - impedance design without a resistor box, cold - machined tips for precision, ultra - fast solenoids for accurate fuel metering, linear response in 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 and idle quality.

Using these fuel injectors is easy. First, make sure your vehicle is turned off and cooled down. Then, carefully replace the old injectors with these Grams Performance ones according to your vehicle's manual. When tuning your engine, use the dead - time compensation values provided with the injector set to get the best air/fuel ratio. Here are some important notes. Avoid using these injectors with fuels that contain unknown or untested additives as it might affect the O - rings. Don't expose the injectors to temperatures beyond their specified range. For maintenance, regularly check the O - rings for signs of wear or damage. If you notice any fuel leaks or a drop in engine performance, it's a good idea to inspect the injectors. You can clean the injectors periodically using a recommended fuel injector cleaner to keep them in top shape.
