Radium Toyota Air Assist Injector Seat, Single

The Radium Engineering 20-0516 Toyota Air Assist Injector Seat converts Toyota air-assist injectors to standard top feed injectors. It is the same machined aluminium seat used in many Radium Engineering fuel rails.

The seat press-fits into the intake manifold injector port with no modification required. The included FKM O-ring seals into the machined injector counterbore to prevent vacuum or boost leaks, and the bore suits a common 14mm lower injector O-ring.

Note: Sold individually (not a set) — order one per cylinder.
