Low and High Impedance Injectors: Size and Flow Rates

It is hard to discuss high and low-impedance injectors without bringing size and flow rate into the picture. In layman’s terms, static flow refers to the maximum fluid amount an injector flows at an open operation. Contrary to misguided misconception, a bigger size does not mean it can support your specific situation. Instead, don’t choose a small or large fuel injector that might not meet your requirements. Depending on your needs, there are downsides to picking small and large injectors.  

For instance, extremely small injectors can trigger a lean engine condition. And when it comes to extremely large injectors, the operational functionality of the injector gets compromised due to non-linear range and oversizing.

INAT Auto Parts has focused on high impedance fuel injectors for car upgrades over ten years, including popular flow rates such as 850cc, 1000cc, 1050cc, 1200cc, 1250cc, etc. These injectors can be used for E85 fuel and can effectively increase vehicle power. They are capable of operating at high fuel pressures and do not suffer from the high fuel pressure handling issues present with many other high flow, high impedance injectors. In addition, we have an ASNU test machine to conduct a strong test on the injector before leaving the factory, and the dynamic flow rate is matched within 1%.
