Product Information
Part #: G2 - 0550 - 1200. Each injector is individually balanced, flow - tested, and precisely matched within one percent of each other. Pressure - tested up to 220 psi, it ensures leak - free operation and top - notch performance. You'll get amazing cylinder - to - cylinder consistency, even at low pulse widths, along with excellent idle quality, response, and overall performance. The ultra - fast and accurate solenoids have a linear response curve across various operating conditions. They can precisely meter fuel even at high pressures and short pulse widths. These injectors are cold - cut with diamond grinders in under three seconds for high precision, no need for 'pre - seating'. 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. Rigorously tested in labs and on dynos, streets, and race tracks, they perform great in extreme conditions. Features: High - impedance design without a resistor box; Cold - machined tips for high - precision; Ultra - fast solenoids for accurate fuel metering; Linear response in a wide range of conditions; All injectors balanced and matched within one percent; Compatible with all known fuels like gasoline, methanol, and ethanol; Unbeatable cylinder - to - cylinder consistency and optimal idle quality.
Using these Grams 550cc fuel injectors is straightforward. First, make sure your vehicle model (2002 - 2014 Subaru WRX, 2007 - 2020 STI, 2007 - 2011 Legacy GT, 2004 - 2013 Forester XT, or 2007 - 2009 Outback XT) is compatible. Then, install the injectors according to your vehicle's standard installation process. When it comes to fuel, you can use gasoline, methanol, or ethanol without any worries. For maintenance, keep an eye on the performance of your engine. If you notice any changes in idle quality or engine response, it might be time to check the injectors. Also, since they are pressure - tested up to 220 psi, don't subject them to pressures beyond this limit. And remember, these injectors are already balanced and matched, so avoid any unnecessary tampering. If you need to tune your vehicle, use the dead time compensation values provided with the injector set for better results.
