Boomba WRX/STI Fuel Rail
The next generation of fuel rails is specially designed for Subaru WRX. The rail is made of CNC machined aluminum. The fuel rail has large 12.7mm internal bores (compared to previous version 8.75mm bore) and larger AN-6 threaded ports (previous version used 1/4 NPT ports). It is available in natural aluminum, blue, black and red anodized finishes. The kit guarantees even fuel distribution by redirecting the fuel to all cylinders. This action should enhance the performance and add more power to the engine. The rail not only boosts the power but also upgrades the visual effect. Adaptor fittings are sold separately, see fittings page for more details.
For top feed applications only.
In order to complete installation, several fittings will also be needed (not included):
(8) x AN6
(1) x AN8
