Fuel Injector Adapters & Injector Fitment Hardware
Fuel injector adapters allow you to install fuel injectors with different physical dimensions, electrical connectors, or mounting styles into a fuel rail or intake manifold that wasn't originally designed for them. Adapters are essential when upgrading to larger injectors from a different manufacturer or swapping to a different injector style for more flow on a performance build.
OneFastShop carries fuel injector adapters including injector height adapters, injector hat adapters, injector spacers, O-ring conversion kits, top-feed to side-feed adapters, and fitment hardware for popular injector sizes and fuel rail configurations.
Every injector adapter at OneFastShop ships brand-new and ready to install. Whether you're fitting larger injectors into a stock fuel rail, converting injector styles for a swap, or resolving height differences between injectors and rails, OneFastShop has the adapter.
