PERRIN Performance™ manufactures the #1 Subaru STI fuel rail in the automotive world

The PERRIN™ fuel rails represent a true advancement in boxer engine fuel delivery. The PERRIN™ fuel rail kit is not just a replacement part. We have completely redesigned and redirected the fuel from the supply lines to the injectors. The PERRIN Performance™ Subaru fuel rail kit solves all fuel distribution problems dividing fuel evenly between the fuel pressure regulator and both banks of cylinders in the boxer engine.

PERRIN Performance™ fuel rails are specifically designed for the STI to side feed injectors.

PERRIN Performance™ fuel rails use high tensile, stainless steel fuel line constructed of an extruded Teflon liner incased inside a tightly woven stainless steel outer braid. Teflon lined fuel lines are completely impervious to any automotive fuel. Fuel line diameter is increased from 7/32 inch to 3/8 inch To increase flow rates. PERRIN™ Fuel rail kits are Pre-assembled using permanent crimp connectors which hold over 400 PSI.
