Using these DeatschWerks fuel injectors is easy. First, make sure your vehicle is the 2004 - 2006 STI or 2005 - 2006 Legacy GT as specified. Install the conversion kit following the basic automotive installation steps. Since it's a 100% drop - in design, it should fit right in. When using, note that the injectors are fully anodized for e85 compatibility, so you can use e85 fuel safely. For maintenance, regularly check the -6 AN in and out ports for any signs of blockage or leakage. If you notice any issues, have it inspected by a professional mechanic. You can choose different injector capacities according to your vehicle's performance needs, like 850cc, 1200cc, or 1500cc, but make sure it suits your engine requirements.
