V3 Top Feed Fuel Rails (Gold Finish) – IAG-AFD-2102GD For Cheap

The IAG Performance V3 Top Feed Billet Aluminum Fuel Rails with phenolic spacers are designed to increase the power ceiling on your Subaru s fuel system. The factory fuel rails function in a series, which means that each cylinder s fuel is delivered after the other. As horsepower rises past the 350whp mark, the stock rail often does not have the capacity to deliver fuel to the last cylinder effectively. As a result, that last cylinder can run lean, which can result in catastrophic failure. The IAG billet fuel rails are designed to eliminate this problem. First, our fuel rails operate in parallel format, each cylinder bank receives equal fuel, matching the flow between the rails ensures that each injector sees the same fuel pressure. Second, the bore of our rail is machined to 5 8 ID and is designed to accept -8 O-ring boss fittings. This configuration greatly increases the volume of the rail which means that more fuel is available at higher power levels and IAG s fuel rails were real-world tested to 1000hp. All IAG fuel rails are engineered and manufactured at the IAG facility in Westminster, Maryland. The rails are machined from a solid 6061 billet aluminum and feature an anodized Gold finish with the IAG logo engraved on the top..
