RADIUM TOP FEED FUEL RAIL ADAPTER (WRX/STI 2001+)

There are no high flow fuel rails available for the JDM (Version 8/9) STi Spec C engines which have the long runner intake manifold (no tumble generator valves). This adapter permits the use of any 2002+ Subaru top feed fuel rail. Furthermore, it was specifically designed for the Radium 20-0167-01 and 20-0167-02 Upgrade Fuel Rail kits that use a Radium 20-0176 Fuel Pulse Damper (shown below).

This adapter IS NOT compatible with side-feed fuel rails or side-to-top feed conversion rails.
