The Radium Engineering High Flow Fuel Filter Kit is a direct OEM replacement for the factory Nissan fuel filter, plumbed between the fuel pump and fuel rail. CNC-machined from 6061 aluminium and Type-II anodised for maximum corrosion resistance, the 3-piece body features large 10AN ORB female threaded ports on both removable end caps for high-flow plumbing. Viton O-ring seals ensure compatibility with all fuel types including gasoline, diesel, methanol, ethanol, and E85.

The large 4.2" x 1.75" filter element maximises flow without sacrificing filtration, and holds significantly more contaminants than OEM before becoming a restriction — resulting in a very long service life. Because the Radium filter is less restrictive than the OEM Nissan unit, there is less stress on the fuel pump, lower pre-filter pressures, reduced current draw, lower fuel temperatures, and an increase in overall fuel flow.

Installation takes less than an hour. No cutting or drilling required.
