Product Description

The PERRIN High-Flow Fuel rails for the Subaru WRX and STI are designed to deliver large amounts of fuel equally to each cylinder. Consumers running big horsepower that require large injectors will notice the car runs smoother and is more powerful and tuners can safely push the engine closer to the edge.

High-Flow & -6 Fittings
PERRIN High-Flow Fuel Rails incorporate large inside diameter channels for maximum fuel flow. This allows for cars to run 800 WHP without inconsistent fuel flow to each cylinder. We include custom made -6 barbed fittings with O-rings to ensure a proper connection to the hose. These fittings are removable allowing for easy customization of aftermarket fuel lines.

Equal Length
The equal flowing nature of PERRIN Fuel Rails allow your high powered Subaru to make more power, safer. A must have for any car looking to exceed 400 horsepower. PERRIN High-Flow Fuel Rails split incoming fuel for equal fuel distribution, pressure, and more consistent air fuel ratio between all cylinders. The stock fuel rails route the fuel through the engine bay sequentially providing each injector with fuel. In modified Subarus, this drastically reduces fuel delivery to the last injector in line.

Complete Kit
The PERRIN Fuel Rails and distribution block are precision CNC machined from 6061 billet aluminum. Each -6 Barbed Fitting is removable from the rails and distribution block allowing for easy customization of aftermarket fuel lines.

Phenolic Spacers
All PERRIN High-Flow Fuel Rails come with built-in phenolic spacers. The spacers fitted to fuel rails and junction blocks sit between these and the engine, insulating it from heat. This keeps fuel closer to its normal ambient temperature. In contrast, without these spacers, you can see fuel temperatures rise far more than 30 degrees above ambient.

Construction
The PERRIN Fuel Rails and distribution block are precision CNC machined from 6061 billet aluminum with black anodized finish for corrosion protection. All parts are marked with Feed and Return for easier installation.

Finish

PERRIN Fuel Rails are anodized with a black finish for corrosion protection. Our fuel hose sleeve features a PERRIN logo. Each rail and distribution block is stamped with a vibrant PERRIN logo dressing up any engine bay.
