Adjustable Fuel Regulator Kit with PTFE Fuel Lines

This comprehensive kit includes everything needed to ensure adequate fuel flow for significant horsepower gains. The core components feature IAG's chemical-resistant PTFE fuel lines, which are designed for easy installation without the need for cutting or hose assembly, and are fully compatible with modern ethanol fuels, including E85. The lines are constructed to prevent fuel vapor permeation, thereby eliminating the common issue of fuel smell often associated with other line types. Central to the kit's performance is the included Aeromotive Adjustable Fuel Pressure Regulator, renowned for its consistency and reliability in managing fuel pressure. Complementing this are the IAG High Flow Fuel Rails, tested to support over 1000 horsepower and designed to work with most aftermarket top-feed injectors. These attractive fuel rails are available in various finishes, including the red finish specified by this particular kit (IAG-AFD-2600RD), adding a custom aesthetic to the engine bay. Installation notes indicate that aftermarket TGV housings are required for proper fitment. This system is designed for 2008-2014 Subaru WRX and 2008-2021 Subaru STI models.
