Holley 522-421 - Holley Fuel Injectors

When adding horsepower, don't forget to accommodate more fuel... a must when modifying your engine with camshafts, heads, headers, fuel systems, forced induction and so on.

Holley Fuel Injectors are available in low or high impedance and sold in 1/pkg or 8/pkg quantities. These top-fed, bottom outlet Holley/Delphi performance fuel injectors are quality replacements for Holley Commander 950, HP and Dominator multi-point injection systems and can be used in many factory and aftermarket applications!
