Radium FPD-R Inline Fuel Pulse Damper Kit - 10AN Ign2a NOTE: Radium Engineering coolant expansion

NOTE: Radium Engineering coolant expansion tanks require a Type-A style radiator cap

they are easy to set up and tooth gap is also not as critical as 'reluctor' type kits

Now you can effectively baffle the top end of the notoriously heavy breathing RB with some high volume cam covers

Radium FPD-R Inline Fuel Pulse Damper Kit - 10AN Ign2a NOTE: Radium Engineering coolant expansionThe opening and closing of fuel injectors creates pressure pulses in the fuel rail which can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow injectors. Furthermore,
