Holley is pleased to announce the release of awesome new products this week. Holley's popular Terminator X EFI systems can now benefit from new 220 LB/HR fuel injectors.
Terminator X High Impedance Fuel Injectors feature a precision lapped disc valve, high-quality brass windings, and high-temp o-rings. These injectors provide excellent linearity with no discernible "bounce" at low pulse widths as commonly found in other injectors. With a wide variety of fuel flow offerings from 42 lb./hr. to 220 lb./hr. (441 cc/m to 2310 cc/m) you are sure to find an injector that matches your non-emissions controlled application. These high quality fuel injectors can also be used with any ECU that utilize high impedance fuel injector drivers.
