3.2 Fuel Injector
- F1ZE-9F593-C2A, 19 Lb/Hr
Many Ford 302/351 fuel injected engines are factory equipped with a set of 19# Fuel
Injectors, which will safely support approximately 275 HP. If you have made horsepower
improvements, you will need to consider larger fuel injectors.
3.3 Mass Airflow Sensor
- F1ZZ-12B579-AA
If you choose a larger injector than the factory 19 lb/hr, you will need an aftermarket
mass air meter calibrated for that size injector.
