Part #: 02J - 00 - 1000 - 4. These Deatschwerks side - feed injectors from 2004 - 2006 come with flow rates ranging from 550 to 1000cc. They use an OEM 12 - orifice atomization plate (except 550s and 650s with a 4 - hole version). Note that these are for 2004 - 2006 STI models only; 02 - 07 WRXs and 2007 STIs need top - feed injectors. They're suitable for 2004 - 2006 STI, 2005 - 2006 Legacy, and 2004 - 2005 Outback XT. The injectors are sold in sets of four and ECU tuning is required.


Using these Deatschwerks 1000cc side - feed injectors is a great way to enhance your vehicle's performance. First, make sure your car is one of the compatible models like 2004 - 2006 STI, 2005 - 2006 Legacy GT, or 2004 - 2005 Forester XT. When installing, keep in mind that they come in sets of four, so install all of them at once. After installation, you must get the ECU tuned to ensure proper functioning. As for maintenance, regularly check for any signs of leakage or clogging. If you notice any issues, it's best to have a professional take a look. Also, remember that these are only for the specified models, so don't try to use them on 02 - 07 WRXs or 2007 STIs as they require top - feed injectors.
