The HOLLEY 220 PPH Fuel Injectors 8-pack High Impedance represents a flow-matched EV6 universal injector set engineered for modern fuel injection tuning and engine management applications. At 220 pounds per hour flow rate, this eight-injector configuration delivers the precision fuel atomization required for stable idle quality, responsive throttle response, and optimized combustion across the full RPM spectrum in carbureted-to-EFI conversions and performance fuel system upgrades.
High impedance design allows compatibility with most aftermarket ECUs and traditional fuel injection harnesses without requiring resistor boxes or additional wiring modifications. The 220 lb/hr rating sits in the sweet spot for mid-range displacement engines—sufficient for modest boost or naturally aspirated applications requiring consistent fuel metering without oversizing that would sacrifice idle control and part-throttle driveability. Flow matching across all eight injectors ensures balanced cylinder charging and eliminates lean/rich conditions caused by injector variance. The EV6 connector design provides a secure fit and is widely supported across Holley Terminator X systems and other modern engine management platforms.
This eight-pack configuration is purpose-built for V8 engines and is the correct choice for builders standardizing on Holley fuel injection systems or upgrading existing carbureted platforms. The universal EV6 fitment reduces guesswork during installation, and the pre-matched set minimizes tuning variables when mapping fuel tables in your engine control unit.
Whether you're configuring a street-performance V8, EFI-converting a classic, or fine-tuning an existing fuel system, matching injector size and flow rate to engine displacement and boost level is non-negotiable for reliable cold starts, smooth idle, and repeatable power delivery across gear shifts and load transitions.
TacticalSurplusUSA stocks the HOLLEY 220 PPH High Impedance Fuel Injectors as a complete ready-to-install set, eliminating the need to source individual injectors and verify flow matching yourself.
