Description
Radium Injector Seats, Nissan, 25mm / 30mm
Application: Nissan KA24DE, SR20DET, SR20VE and RB25DET (non-NEO) top feed conversions
Part Type: Injector seat (sold individually)
Part Number: 20-0161, 20-0160
These are the same machined aluminium injector seats Radium uses in its Nissan fuel rail kits. They are required when converting an OEM side-feed injector to a top-feed injector that uses a 14mm lower O-ring.
One seat presses into the intake manifold per injector and seals against the machined injector counterbore with the included FKM O-ring. Because the seats suit different engines they are sold individually – order one per injector.
Key Features
- Material: CNC machined 6061 aluminium
- Finish: Bright dipped anodised with laser etched logo
- Injector Bore: Common 14mm bore for the lower injector O-ring
- Seal: FKM O-ring included
- Installation: Press-fit into the intake manifold injector port
Available Configurations
- 20-0161: 25mm seat, Radium green anodised – Nissan RB25DET (non-NEO), SR20DET S14, SR20DET S15, SR20VE FWD
- 20-0160: 30mm seat, black anodised – Nissan KA24DE S13, KA24DE S14, SR20DET S13
What's Included

Important Notes
- Sold individually – order one seat per injector
- Clean any dirt or debris out of the manifold injector seat bores, lubricate the O-rings with O-ring lube, petroleum jelly or motor oil, then press the seats in until fully seated (a small rubber mallet can help)
