Upgrading fuel systems is an important supporting modification when looking for big power gains from turbo or engine upgrades. At PERRIN Performance, we make high-quality top-feed fuel rail systems for WRX and STI builders looking for more fuel flow.
In addition to full fuel rail systems, we also offer pressure regulators and fuel pumps to provide additional flow and ethanol compatibility. When upgrading to E85 in your WRX, STI, BRZ, or 86, our fuel system upgrades a must-have.
