Upgrading your vehicle’s fuel systems is an important, often overlooked modification when looking for big power gains from your 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. If you’re looking to upgrade to E85 in your WRX, STI, our fuel system upgrades are a must-have.
