FAST Fuel Air Spark Technology 30667-8 Details

FAST Precision-Flow Fuel Injectors deliver the outstanding idle quality, unparalleled flow consistency, and durability essential for high performance EFI applications. Engineered for excellent response and fuel atomization, Precision-Flow Fuel Injectors are manufactured and 100% flow tested to maintain the tightest tolerances in the industry. These injectors go through a multi-point dynamic flow testing process that holds them to within +/- 2% of the stated flow rate. Testing at multiple pulse widths, instead of just at static flow, ensures consistent cylinder to cylinder fuel delivery through the whole operating range of an engine, not just at maximum capacity. The result is a smoother operating engine that is easier to tune and maintain a consistent cylinder to cylinder air/fuel ratio.
