Radium Engineering Injector Seats for Top Feed Conversion Fuel Rails - Nissan SR20DET/RB25DET

Radium Engineering builds fuel system hardware to motorsport-grade tolerances, and these injector seats are the same components used in Radium's own Nissan fuel rail kits. CNC-machined from 6061 aluminium and finished with a laser etched logo, they give your top feed conversion a proven, leak-free base for aftermarket injectors on the SR20DET and RB25DET.

This listing covers seats for the SR20DET (S13), SR20DET (S14/S15), RB25DET, KA24DE (S13/S14) and SR20VE FWD applications. Seats are available in 30mm black anodised or 25mm green anodised, in sets of 4 or 6 — select the correct size and quantity for your manifold using the options on this listing.

Important: the 30mm and 25mm seats are not interchangeable. Measure your intake manifold's injector counterbore before ordering to confirm the correct size for your application.
