What does 'low impedance' mean for these injectors?

Low impedance injectors have a lower electrical resistance, which allows them to open and close faster. This can lead to more precise fuel control, especially at higher RPMs or with more aggressive tuning.

Are these injectors compatible with my stock ECU?

Low impedance injectors often require an injector resistor box or an ECU that can handle low impedance operation. It's best to consult your engine management system's specifications or a tuning professional to ensure compatibility.

What else might I need when installing these injectors?

When upgrading fuel injectors, it's often recommended to also check or upgrade your fuel pump and fuel filter to ensure they can keep up with the increased demand. You may also need new injector seals or O-rings for a proper installation.

Product Details

If you're looking to upgrade the fuel system on your 1986-1987 Mazda RX-7, especially if you've modified the engine or are planning more power, a set of higher-flow fuel injectors is a key component. These DeatschWerks injectors are designed to deliver 800cc of fuel per minute, which is a significant increase over stock, making them suitable for boosted applications or engines with more aggressive tuning.

This set includes two matched injectors, ensuring consistent fuel delivery to each rotor. They are low impedance, which is important for compatibility with certain engine management systems and allows for quicker response times. DeatschWerks is known for their fuel system components, and these injectors are built to handle the demands of performance tuning.
