Injector Dynamics ID1750x Fuel Injectors
The best just got better! Injector Dynamics ID1750x fuel injectors are a built-to-spec motorsport injector, offering optimization of critical operating parameters important to you, the motorsport tuner. Built on the evolution of the ID1700 and X Series, these fuel injectors are a drastic improvement over previous series from Injector Dynamics. Compared to the 1700, the 1750x offers: higher dynamic flow rate with no increase in minimum fuel mass, better cylinder to cylinder balance at low pulse widths, and improved pressure sensitivity—all while retaining the same "compatible with everything but dirt" corrosion resistance that made the ID1700 famous. Plus, a unique magnetic circuit, resulting from a lengthy development program, makes the ID1750x immune to voltage and pressure sensitivity problems that plague other high impedance high flow injectors. Order the set of fuel injectors recommended for your vehicle. Key features and benefits include: * Compact body design allows fitment in a variety of applications * Higher dynamic flow rate with no decrease in minimum fuel mass * Better cylinder to cylinder balance at low pulse widths * Improved pressure sensitivity * Corrosion resistance makes these fuel injectors compatible with Methanol/Ethanol/MTBE/Nitromethane and all known Hydrocarbon fuels * Unique magnetic circuit makes the ID1750x immune to voltage and pressure sensitivity problems that plague other high impedance high flow injectors * Narrow spray pattern—minimal wall wetting promotes quick response and smooth running * Does not require extended linearity at low flow rates
