The PERRIN Performance™ fuel rails represent a true advancement in boxer engine fuel delivery.

The PERRIN Performance™ fuel rail kit is not just a replacement part. We have completely redesigned and redirected the fuel from the supply lines to the injectors, thus solving all fuel distribution problems insuring even fuel distribution to both banks of cylinders in the boxer engine.

As clients continue to expand the HP in their vehicles this need for even fuel delivery is more critical. Failure to address this concern and your expensive motor will quickly require some major attention.

To further prove our distinction as the industry leader in Fuel rail technology for Subaru applications, we now include DOT approved fuel lines and PERRIN Pyroshield™! This fire retardant sleeve is placed over the fuel hose to protect the fuel lines from being subjected to extreme underhood heat created by high horsepower turbocharged monsters. This lowers the fuel temps, thus improving horsepower and increasing longevity.

Available in Black with aluminum PERRIN™ logo plates to suit any engine bay.

Fits: Subaru WRX STi 2004-2007
