Description
Radium Injector Seats — Nissan 25mm & 30mm
Purpose-built machined aluminium injector seats for converting OEM side-feed to top-feed fuel delivery on Nissan engines. Engineered to the same specifications as Radium Engineering fuel rail kits, these seats press-fit directly into your intake manifold counterbore with zero modification required. The 14mm lower O-ring design pairs with the included FKM seal for consistent, leak-free performance across all fuel system pressures.
Sold individually (singles) — order one seat per cylinder to match your engine configuration.
