Fuel Lines & Filters

Shop Subaru fuel lines and filters at IAG Performance for WRX and STI models, including IAG Performance PTFE fuel line kits and complete fuel system kits with injectors, lines, fuel pressure regulators, and fuel rails, plus COBB flex fuel-compatible setups. These PTFE-lined lines resist swelling and degradation from ethanol blends better than standard rubber lines, making them a smart upgrade for E85 and flex fuel conversions. These components are a core part of any fuel system upgrade.
