AUS Injection has been manufacturing and refurbishing injectors for years now, and we've worked closely with them to bring this injector to the market. The AUS 550cc Injector differs from other redrilled/modified injectors in several ways:

• 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.
• 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 550 Injector E85-compatible.

AUS Injectors carry a 3-year warranty, and necessary O-rings are included along with a true flow-test data sheet, specific to the injectors you receive.

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.
