Product Information
Part #: G2 - 0550 - 0700. Each injector is individually balanced, flow - tested, and dynamically matched to ensure they're within one percent of each other. We pressure - test each injector 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, along with great idle quality, response, and performance. These fuel injectors have ultra - fast and precise solenoids with a linear response curve under various operating conditions. They can accurately meter 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. Abrasive cutting generates heat, causing poor spray patterns, but our method avoids this. Each injector comes with high - quality Viton O - rings resistant to extreme temperatures and harmful oils in some fuels. Every injector set includes dead - time compensation values for consistent air/fuel ratios and optimal performance during tuning. These fuel injectors are carefully tested and matched in controlled lab environments using advanced equipment. They also go through tough dyno, street, and race - track testing 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 operating conditions, all injectors balanced and matched within one percent, compatible with all known fuels like gasoline, methanol, and ethanol, and unmatched cylinder - to - cylinder consistency with great idle quality.
Using these Grams Performance 550cc fuel injectors is easy. Just install them in your Nissan 350z (2003 - 2009) or Infiniti (2003 - 2007) according to your vehicle's standard installation process. When tuning your vehicle, make use of the dead - time compensation values included in each set to get the best air/fuel ratios. As for maintenance, it's a good idea to check the Viton O - rings periodically for any signs of wear or damage. If you notice any issues with the injectors, like inconsistent performance or poor idle quality, have them inspected by a professional. These injectors are built to last, but like any part, they need a bit of care. Make sure to use compatible fuels, such as gasoline, methanol, or ethanol, to keep them working at their best. And always follow your vehicle's regular maintenance schedule to ensure the overall health of your engine.
