Using your Radium DPI fuel rails is straightforward. First, make sure your vehicle is a 2002 - 2014 Subaru WRX and you're using Radium Fuel Rail Housings. For the primary lower fuel injectors, if you're using OEM Subaru injectors, put the provided top hat over the upper O - ring. If you choose 60mm Bosch EV14 style injectors, just use the provided adapters. For the secondary upper fuel injectors, only 34mm Bosch EV14 style ones work. When installing, use the included stainless steel hardware and FKM O - ring seals. Also, don't forget to install the thermal insulating press - in spacers. Note: These fuel rails are only for Radium Fuel Rail Housings. To maintain your fuel rails, check the O - ring seals regularly for any signs of wear. Keep them clean and away from dirt and debris. Since they're compatible with all fuel types, you don't have to worry about fuel - related damage, but it's still a good idea to use high - quality fuel. If you have any issues, consult a professional mechanic.
