What does 'high impedance' mean for these injectors?

A high impedance injector has a higher electrical resistance. This means it can be wired directly to your vehicle's stock ECU without the need for an external resistor box, simplifying installation.

Will I need any special tools to install these injectors?

You will need basic hand tools for removal and installation. A wire splicing tool and appropriate connectors will be necessary to connect the included EV6 pigtails to your vehicle's wiring harness.

Are these injectors compatible with all performance modifications?

These 550cc injectors are suitable for many performance upgrades that increase fuel demand. However, for highly modified engines or specific tuning requirements, it's always best to consult with your tuner to ensure they meet your exact needs.

Product Details

These Grams Performance 550cc fuel injectors are built with a high impedance design, meaning they'll work directly with your stock ECU without needing an external resistor box. This is a solid choice if you're looking to upgrade the fuel system on your 2003-2009 Nissan 350Z or 2003-2007 Infiniti G35, especially if you've made other performance modifications that require more fuel flow than the factory injectors can provide.

Grams Performance uses advanced manufacturing techniques and premium materials to create these injectors. They're designed to flow a consistent 550cc per minute, which is a notable increase over stock, helping to ensure your engine gets the fuel it needs for improved performance. While they are a direct fit for the specified vehicles, you will need to splice the included EV6 pigtails into your existing wiring harness. This is a common step when upgrading to higher-flow injectors and ensures a secure connection.

This set includes all six injectors needed for your VQ35 engine. Keep in mind that these injectors are not CARB approved and cannot be shipped to California. If you're building a more powerful engine, having a fuel system that can keep up is crucial, and these injectors are a well-built option to consider.
