MSI SUB-01-05-001 Fuel rails SUBARU IMPREZA WRX / STI 2001-2007 (Top feed)

Description

Larger power requires more fuel.

What is not simple is the fuel rails. The stock rails are plumbed in series, and really don't have much reserve capacity. This means you run the risk of leaning out injector number 4 when you have big fuel requirements. This can mean bad things.

The MSI fuel rails run in parallel and have a much higher rail capacity than OEM.
