The PERRIN High-Flow Fuel rails 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. 

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.

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.
