Product type
EFI fuel injectors are essential components in modern internal combustion engines, responsible for delivering fuel directly into the combustion chamber. They are typically made from durable materials such as stainless steel and plastic, designed to withstand high pressures and temperatures. EFI stands for Electronic Fuel Injection, which means these injectors are controlled electronically to optimize fuel delivery for efficiency and performance.
| Material | Stainless steel and plastic |
| Flow rate | Typically ranges from 100 to 800 cc/min |
| Operating pressure | Usually between 30 to 60 psi |
| Connector type | Varies by application, commonly EV1, EV6, or EV14 |
| Resistance | Typically 12 to 16 ohms |
When selecting EFI fuel injectors, consider the specific flow rate required for your engine's performance needs. It's important to specify the connector type and resistance to ensure compatibility with your vehicle's wiring harness. Additionally, inquire about any necessary certifications or standards that may apply to your application, especially for racing or performance use. Quantities can vary based on whether you are replacing a single injector or an entire set.
