IAG Performance PTFE Fuel Line Kit for use w/ Cobb Flex Fuel Kit 2008-2014 WRX / 2008-2021 STI

When designing the IAG Fuel Line Kits our goal was to take the worry and confusion out of properly setting up Subaru fuel delivery. The IAG Fuel Line kits provide everything you need to successfully feed your engine with enough fuel to meet your horsepower demands. Made in the USA and constructed of chemical resistant PTFE, these line kits are easy to install and don’t require any cutting or hose assembly. Each line kit is compatible with modern ethanol fuels, including E85. These kits are designed to work with aftermarket Fuel Rails and the aftermarket Adjustable Fuel Regulator, for precise control of your fuel pressure.

The IAG Fuel Line Kits are compatible with OEM or IAG TGV housings with sensors and motors installed. No modification to the tumble generator valve assemblies or components are required for installation. Fuel Rails are required for installation.

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of applications, though it’s perhaps best-known for its non-stick properties. This means that the fuel lines don’t allow permeation of fuel like traditional braided lines and wont deteriorate over time when exposed to ethanol.

Included in these kits are extra hoses to attach to the popular continental flex fuel sensors used in many common flex fuel kits. The push-to-connect fittings make installation easy and allow for precise control of your engine based on the ethanol content of your fuel when used with a poperly equipped flex fuel kit such as the one sold by COBB Tuning.
