Show original supplier description
The IAG PTFE Fuel System Kit is engineered to simplify and enhance the fuel delivery system for 2008-2014 Subaru WRX and 2008-2021 Subaru STI vehicles. The primary goal of this kit is to provide a complete solution that ensures your engine receives adequate fuel to meet demanding horsepower requirements, eliminating the guesswork often associated with fuel system upgrades. Constructed from chemical-resistant PTFE, these fuel lines are designed for durability and compatibility with modern ethanol fuels, including E85. This material prevents fuel permeation common in traditional braided lines and resists deterioration over time. The kit's components are made in the USA, ensuring quality manufacturing. Installation is straightforward, as the PTFE line kits do not require any cutting or hose assembly. Each kit includes IAG Fuel Rails, tested to support over 1000 horsepower, and an Aeromotive Adjustable Fuel Pressure Regulator, known for its consistent and reliable performance. Buyers can also select from various Injector Dynamics fuel injector options (1050, 1300, 1750, and 2600cc) to match their specific power goals, with recommendations to consult a tuner for the best fit. The fuel rails are available in Black, Red, or Gold to complement engine bay aesthetics. The kit also includes a fuel line kit and an Aeromotive Adjustable Fuel Pressure Regulator.
