Description
HPI M8 fuel injectors deliver precise and consistent fuel delivery for Harley-Davidson Milwaukee-Eight engines. Riders who upgrade intake systems, install performance exhausts, or build higher-output motors need injectors that can support increased airflow and horsepower. These high-flow injectors provide the fuel capacity required to keep engines running strong and responsive.
HPI designs these fuel injectors for M8 engines to maintain stable spray patterns across a wide RPM range. As a result, throttle response improves, power delivery feels smoother, and the engine operates more reliably under demanding riding conditions. Because accurate fueling matters in performance applications, this injector upgrade helps protect engine health while maximizing output.
