Perrin's newly redesigned STi (V2) Fuel Rails are a true advancement in fuel delivery for your Subaru boxer engine. Perrin's V2 STi Fuel Rail systems redirect the fuel from the supply lines to the injectors, solving all fuel distribution problems and insuring even fuel distribution to both banks of cylinders. Too often, fuel delivery is overlooked as tuners increase the performance of their Subaru boxer engine and Perrin has made it easy to get the fuel you need more than ever into the combustion chambers.

Perrin's V2 STi Fuel Rail Kits are easier to install and, more importantly, safer than ever before. A major advancement in the fuel rail system's fuel delivery is Perrin's decision to include genuine Goodyear DOT approved fuel lines and Perrin Pyroshield fire retardant sleeving which is placed over fuel hoses and protects the hoses (and the fuel they carry) from underhood heat.

The reduction in fuel temperatures improves horsepower and increases engine life. The Perrin STi V2 Fuel Rail Kits are available with either black or silver rails and junction blocks and include aluminum Perrin logo plates to dress up your engine bay. Perrin STi Fuel Rail Kits include instructions, two (2) Black or Silver Fuel Rails, one (1) Black or Silver Junction Block, Perrin Pyroshield, Goodyear DOT approved Fuel Hose and all fittings and hardware for complete installation.
