Fitment Information: This product fits 2002 - 2014 Subaru WRX, 2007 - 2021 Subaru STI, 2008 - 2012 Subaru Legacy GT, and 2006 - 2013 Subaru Forester XT. Please note: Aftermarket lines and fittings are needed to install IAG Fuel Rails and can be bought separately. It's confirmed to work with Injector Dynamics. Process West TGV Deletes might need 5mm shorter bolts (not included) to work with these fuel rails. Features: The IAG Performance V3 Top Feed Billet Aluminum Fuel Rails with phenolic spacers boost your Subaru's fuel - system power. Factory fuel rails work in series, which may lead to the last cylinder running lean at over 350whp and cause failure. The IAG rails operate in parallel, ensuring each cylinder bank gets equal fuel and the same pressure. With a 5/8' ID bore and designed for - 8 O - ring boss fittings, they increase fuel volume and are tested to 1000hp. There's a port for a fuel pressure pulsation damper between injectors to maintain constant pressure. Phenolic spacers between the rails and TGV's reduce heat transfer from the engine to the fuel. Other features include CNC machining from 6061 billet aluminum, anodized finish in Black, Red, or Gold, engraved IAG Logo, 2 - piece mounting design with phenolic thermo spacers, recessed mounting hardware, and being engineered and manufactured at the IAG facility in Westminster, Maryland. What's in the Box: (2) Billet Fuel Rail, (4) Zinc coated M8x30mm socket head cap bolt, (4) Phenolic Spacers, (4) O - rings, (2) Hex Head Threaded Plug.
Using the IAG V3 Top Feed Fuel Rails is easy. First, make sure you have the necessary aftermarket lines and fittings, as they're not included with the kit. Install the fuel rails following the standard installation process for your Subaru model. When using Process West TGV Deletes, you may need to get 5mm shorter bolts separately. This product is compatible with Injector Dynamics, so you can pair them up if you have those injectors. Regarding maintenance, keep an eye on the fuel dampers. If you notice any fuel oscillations or pressure issues, check the dampers and make sure they're working properly. Also, regularly inspect the phenolic spacers for any signs of wear or damage, as they play an important role in reducing heat transfer. Clean the fuel rails occasionally to prevent any debris build - up. If you plan to use the car at high power levels, these fuel rails are designed to handle up to 1000hp, but still, monitor the fuel system performance to ensure everything is running smoothly.
