2002-16 WRX/STi Perrin Top Feed Fuel Rails


Perrin's High FlowTop-Feed Fuel Rails for the 2008-2010 Subaru WRX are a true advancement in fuel delivery for your Subaru's engine. Perrin's WRX Fuel Rail system redirects 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; Perrin has made it easy to get the fuel you need more than ever into the combustion chambers.

Perrin's WRX High Flow Top-Feed 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 Flexguard high abrasion strength and heat resistant woven ballistic nylon which is placed over fuel hoses and protects the hoses (and the fuel they carry) from excessive underhood heat.

The reduction in fuel temperatures improves horsepower and increases engine life. The Perrin WRX Fuel Rail Kits include instructions, two (2) Black Top-Feed Fuel Rails, one (1) Junction Block, Perrin Flexguard, 3/8" & 5/16" DOT approved Fuel Hoses and all fittings and hardware for complete installation.
