What is the flow rate of these injectors?

Each injector in this set flows 750cc per minute. This is a significant upgrade from the stock flow rate and is suitable for modified engines needing more fuel.

Do these injectors come with everything needed for installation?

This set includes four 750cc injectors with EV6 pigtails. You will need to splice the wiring harness to connect them, and a fuel rail spacer may also be required depending on your specific setup.

Are these injectors compatible with my stock ECU?

These are high-impedance injectors. While they are designed to work with many aftermarket engine management systems, compatibility with your specific stock ECU may vary. It's best to confirm with your ECU manufacturer or tuner.

About this part

Product Details

This kit gets you four 750cc fuel injectors from Grams Performance, designed specifically for your 1990-2005 Mazda Miata with either the 1.6L or 1.8L engine. These injectors are a popular choice when you're looking to upgrade your fuel system to support more power, whether that's from forced induction or other engine modifications. They feature an 11mm top adapter and a Denso-style lower cushion, and they come with EV6 pigtails, meaning you'll need to splice the wiring harness. A fuel rail spacer might also be needed depending on your setup.

Grams Performance uses advanced manufacturing techniques and premium materials to build these high-impedance injectors. This means they're well-built to handle the demands of a performance engine. The 750cc flow rate offers a significant increase over stock, giving you the headroom needed for tuning and making more horsepower. Because they are high impedance, they are compatible with most aftermarket engine management systems without the need for an external injector resistor box.
