Injector Seats 30mm 4cyl. for Nissan Top Feed Conversion Fuel Rails Radium Engineering

These are the same machined aluminum injector seats used in Radium 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. They simply "pop" into the intake manifold (1 required per injector). They seal to the machined injector counterbore using the included FKM O-ring. The 2 sizes are based on the intake manifold's inside diameter of each injector counterbore. Below are just a few examples of some popular Nissan engines.

30mm = KA24DE S13/S14, SR20DET S13
25mm = RB25DET, SR20DET S14/S15, SR20VE FWD

The injector seats are CNC machined with a common 14mm bore for the lower injector O-ring.
