DeatschWerks Universal 550cc Low Impedance 11mm Upper Injector - Set of 4

If you're looking to upgrade the fuel system on your 1985-1991 Volvo 740, these DeatschWerks 550cc injectors are a solid option. They're designed to flow more fuel than stock, which is often necessary when you've made other performance modifications to your engine. This set includes four matched injectors, ensuring consistent fuel delivery across all cylinders.

These are low impedance injectors, meaning they require a specific type of injector driver or resistor box to function correctly with your Volvo's ECU. The 11mm inlet size is a common fitment for many applications, and the 550cc/min flow rate offers a significant increase over factory injectors, making them suitable for tuned engines. DeatschWerks is known for their well-built fuel system components, and these injectors are matched to ensure they perform as a set.

When installing these, remember they are a universal fit, so you may need to adapt your fuel rail or wiring harness depending on your specific setup. Always consult your vehicle's service manual or a trusted mechanic for installation details.
