Radium Fuel Injector Pulsation Damper for OEM Rail
Subaru STI 2015 - 2020
Features & Product Details
RallySport Direct now carries a great selection of high-performance fueling upgrades and accessories brought to you by Radium Engineering.
Here, you are looking at the OEM Style Fuel Pulse Damper.
The opening and closing of the injectors creates pulses in the fuel rail, which can lead to unstable fuel pressure. This damper should be used (especially with high-flow injectors) in order to achieve a safe and consistent rail pressure.
