Introducing the AUS 1100cc Fuel Injectors—an advanced solution designed for high-performance engines demanding precision and power. These injectors stand out with a new, innovative feature: a 12-orifice nozzle that ensures an exceptionally fine fuel spray, promoting superior atomization and optimal combustion. The enhanced spray pattern not only boosts power output and throttle response but also improves fuel efficiency and reduces emissions.

• Flow matched within a 2% tolerance under five different test conditions of varying pressures and duty cycles to ensure even fuel distribution under all driving conditions.
• 12 orifice nozzle that create a fine fuel spray and better combustion.
• Metering plate machined and retained for optimum fuel atomization.
• Revised design locates coil above and out of the path of fuel, protecting the coil from corrosive ethanol. Coupled with stainless steel bodies, this makes the AUS 1100cc Injector E85-compatible.

AUS Injectors come with a 3-year warranty, and necessary O-rings are included along with a true flow-test data sheet specific to the injectors you receive, ensuring precision and quality in every set.

Application
These are New-Style Injectors, which drop right in to new-style fuel rails. If you're looking to install these in a car with old-style rails, you will need an adapter kit. Use the table below to determine if you need an adapter kit to install these injectors. Please note that it is necessary to grind away a small amount of casting on the plenum above the Cylinder #1 Injector Connector when installing new-style injectors with an old-style upper plenum.

If you need the adapter kit, simply add it using the drop-down options above. You can also add new-style injector connectors that can be spliced into your old harness, or use the patch harness for a plug-and-play solution. The adapter kit is also available separately here. We also offer ECU upgrades needed to drive your injector upgrade, available as a full upgrade or EPROM only.
