Description

The IAG PTFE Flex Fuel System Kit simplifies Subaru fuel delivery, providing all necessary components to support high horsepower engines. These lines are specifically engineered to be compatible with modern ethanol fuels, including E85, and prevent fuel permeation common in traditional braided lines, ensuring longevity. This kit includes high-flow IAG Fuel Rails, tested to support over 1000 horsepower, and an Aeromotive Adjustable Fuel Pressure Regulator for consistent and reliable fuel pressure management. It also features Injector Dynamics 1300cc injectors, selected for their quality, dynamic flow matching, and accurate characterization data. Installation compatibility extends to OEM or IAG TGV housings with sensors and motors installed, requiring no modification to the tumble generator valve assemblies. IAG recommends professional installation for this product, though detailed instructions are available for DIY installation referencing the OE Service Manual. This system is designed for 2008-2014 Subaru WRX and 2008-2021 Subaru STI models.
